ow the steps of the successful run when step 1.2 is bypassed (note that the and OpenFOAM session is open in the background while running the Butterfly demo file):
1. create wind tunnel, and use different parameters of (4,4) for _globalRefLevel_ as suggested by Theodoro in this post
2. run blockMesh:
3. run snappyHexMesh:
4. run checkMesh:
5. connect the case from checkMesh to simpleFOAM and run the simulation:
6. the simulation converged at 1865 iteration, but the results visualization part has some problem:
7. so I revised this part according to suggestions from Hagit:
8. and the results can be visualized for P and U values:
The GH file used for the successful run shown above is attached here.
Now, the following is the error I got when the case from the update fvScheme component is used for simpleFOAM simulation:
the warning message on the simpleFOAM component is:

Hope you can kindly advise what the important steps or parameters I might have missed here. I assume it might be related to OpenFOAM rather than with the Butterfly workflow...

Meeting Agenda:
1) Discuss what the group would like to learn this term through our regular scheduled meetings. Topics include the priority and sequence of Grasshopper exercises we would like to explore during the winter term from http://www.digitaltoolbox.info/grasshopper_basic.html and Processing tutorials from the Processing Handbook I received from MIT.
2) Watch the Matt Storus Church Machine video and have a discussion about parametric and generative tools in design.
If you have a chance, please read the following article by Tim Love called Between Mission Statement and Parametric Model at:
http://places.designobserver.com/entry.html?entry=10757
3) Discuss a possible design build project over the following winter and spring terms using the skill set this group is developing. Conversation led by Chris Nielson (please see comments below for a brief backstory)
4) Discuss possible applied research and design work for the National Conference on the Beginning Design Student paper, Machine Craft and the Contemporary Designer: exploring parameters and variables through making physical artifacts. I wrote the attached abstract and submitted it for the conference the past fall and it was accepted. To continue with the research I need to assemble a team of students that will help explore the principles I set forth by making physical objects with the cnc router. In exchange for helping with the research I will show participants how to use the cnc router, how to author machine code and provide you with the cnc controller interface software necessary to simulate machine movements. Not to mention, your work will be sited in the research paper I present at the conference at UNC Charlotte in March. More tomorrow night, of course.
Thank you for your interest and I hope to see you there.
Sincerely,
Erik Hegre

All,
In response to Erik, who requested that I describe my intentions in a design-build project and to the article posted (definitely required reading for this group) I propose that we begin development of a project that spans the realm of "sustainable social" architecture and parametric design. The particulars of such a design do need to be made concrete, and it will be important to define the goals of such a project.
Therefore, I would suggest that this serve as a forum for the next few weeks for those interested in producing a built project. I agree with Nico that it may not be feasible to create the built piece, whatever it may be, this term; however we should have the groundwork and a plan in place by the end of the next 10 weeks.
Either way, I would ask that everyone who is interested to please provide as many concepts to this forum to begin a discussion. If you are indeed interested, please submit goals that this project could achieve (energy, socially, aesthetically, economically, related) and perhaps what you envision the project to physically be (shading device, public bench, water catchment, interactive thermal contraption, etc . . . )
I look forward to hearing your thoughts!
Cheers,
Christopher…
d of interpenetrating surfaces somewhere:
Now all links (except a possible single ball on the very end of odd numbered ball series) are four balls long, including the jostled ones. Without that step, those items simply don't appear in the output, leaving way too big of gaps to ignore, eventually leaving huge gaps at later stages of segment doubling:
So if I turn the jostling multiplication factor way down it should work imperceptibly:
Ta-dah! The jostling strategy WORKS! Granted, only in this special case where I know I'm dealing with adjacent pairs of worms along a curve, not generic objects arranged in space by some artist.
Now I just need to wrap the multiple Python script components I'm stringing together into one script.
How long does the full 2400 balls take, finally? It took 12 Python scripts that merge pairs, to achieve this breakdown: 2400 -> 1200 -> 600 -> 300 -> 150 -> 75 -> 38 -> 19 -> 9 -> 5 -> 3 -> 2 -> 1. Time was 2 minutes 50 seconds, so there is some extra struggle for 2X as many balls as 1200 that took 1 minute 20 seconds, but only ten more seconds.

So, my questions are:

Hope you can kindly advise! Thank you!

ahams's question about how shades are accounted for in the simulation/thermal map and Theodore's thought that just accounting for shades in the E+ run was sufficient. I think that it may be clearest to explain what is going on with this infographic:
As the graphic shows, the thermal maps are made from 4 key types of inputs. The radiant temperature map is formed through a consideration of both the temperature of the surfaces surrounding the occupants and the direct solar radiation that might fall onto the occupants through un-shaded windows. The first surface temperature effect is easily computable from your Energy simulation results and the HBZone geometry. However, the second is calculated by seeing how sun vectors pass through the windows of the zones and uses the SolarCal method of the CBE team (http://escholarship.org/uc/item/89m1h2dg) to compute an MRT delta resulting from solar radiation. This delta is then added to the initial values computed through surface temperature view factor. When you do not connect up your shading brep geometry, internal furniture breps, or outdoor context geometry that might block sun to the additionalShading input, the thermal map will assume that sun can pass unobstructed through the window or through indoor furniture to fall onto occupants. It is important to stress that the EnergyPlus simulation does not count for blind geometry or internal furniture as actual geometry. Just as numerical abstractions of surface area and material properties. So we need you to plug in the actual geometry of these things when we compute the MRT delta resulting from sun falling directly onto people.
Next, to clear up the definition of window transmissivity. The important thing to clarify here is that, whether it refers to the tranmittance of glass or to the amount of sun coming through a fine screen of blinds, the value is multiplied by the radiation falling on the occupant and thus has a direct correlation to the MRT Delta from sun falling on occupants. So, if you set transmissivity to zero, the sun falling on the occupants will not be considered in the calculation and, if you set the transmissivity to 1, the assumption is that there is no window (or the window glass is 100% clear). So, Abraham, your definition of it as a coefficient is appropriate.
Normally, I would just recommend that you leave this value at the default 0.7, which corresponds to the transmittance of the default glass material in Honeybee. However, there are 4 cases in which you might consider changing it:
1) You are not using the default Honeybee glazing material, in which case, you should change the transmissivity to be equal to this new value.
2) You have a lot of really small blind/shade geometries and you do not want the view factor component to take several minutes to trace sun vectors through the detailed shade geometry and so you are ok with using just a simple abstraction instead of plugging shade breps into the additionaShading. In this case, you might try to estimate the average percentage of radiation coming through the blind geometry (maybe with some simple Ladybug radiation studies or with your intuition about the amount of sun blocked by the shades). You will then multiply this by the tranmissivity of your glass and this will be the value that you input to the component.
3) Your blinds for your Honeybee simulation are dynamic, in which case, plugging shade breps into additionalShading is not going to work because the component will assume that those shades are always there. In this case, you should be plugging a list of 8760 values into the transmissivity that correspond to when the shades are pulled. When the blinds are completely up, the value should be the tranmittance of your window and, when they are down, the value should be the window tranmittance multiplied by the fraction of light coming through the shades.
4) You have shades/blinds but they are transparent or are not completely opaque. The additionalShading_ input assumes that all shade geometry is opaque and so you cannot use it to account for such shades. Accordingly, you will need to account for it through the tranmissivity.
In the future, I may try to pull more information about blinds and glass properties off of the HBzones inside the view factor component but, for now and for the next few months, the above describes how it works.
Theodore, for curved geometry, I think that your safest bet is going to be planarizing the Rhino geometry before you turn it into a HBZone (so you just divide the curved surface into a few vertical planar panes of glass that approximate the curve well enough). This is essentially what the runSimulation component does for you automatically (it meshes the geometry as you see here: https://www.youtube.com/watch?v=nMQ2Pau4q6c&index=12&list=PLruLh1AdY-SgW4uDtNSMLeiUmA8YXEHT_). If I were to figure out a way to incorporate shades in this automatic meshing workflow, your EnergyPlus simulation would take a very long time to run and I am not even sure if the result will be that accurate with the way E+ abstracts shades. So I don't think that it's really worth it over just planarizing the geometry yourself.
Lastly, I won't be able to figure out the problem with your current run Theodore, unless I get the GH file from you. Make sure that you are using all up-to-date components.

will work slightly different from before. Sorry about breaking this, but it proved impossible to improve the selection logic with the fairly ambiguous notation that was implemented already.
Not every change is breaking though and I hope that most simple matching rules will work as before. There will be a McNeel webinar on Wednesday the 6th of November where I discuss the new selection rules (as well as path mapping syntax and relative offsets within one or more data trees). This will be a pretty hard-core webinar aimed at expert users. The event will be recorded so you can always go and watch it later. I figured I'd briefly explain the new selection rules on Ning before I release the update though.
-------------------------------------------------------------------------------
Imagine we have the following data tree, containing a bunch of textual characters:
{0;0} = [a,e,i,o,u,y] {0;1} = [ä,ë,ê,ï,î,ö,ô,õ,ü,û,ÿ,ý] {1;0} = [b,c,d,f,g,h,j,k,l,m,n,p,q,r,s,t,v,w,x,z] {1;1} = [ç,ĉ,č,ĝ,ř,š,ş,ž]
There are a total of four branches {0;0}, {0;1}, {1;0} and {1;1}. The first branch contains all the vowels that are part of the standard English alphabet. The second branch contains all non-standard vowels and branches three and four contain the standard and non-standard consonants respectively.
So what if we want to select from this tree only the standard vowels? Basically include everything in the first branch and disregard everything else. We can use the [Tree Split] component with a selection rule to achieve this:
{0;0}
This selection rule hard-codes the number zero in both tree path locations. It doesn't define an item index rule, so all items in {0;0} will be selected.
If we want all the vowels (both standard and non-standard), then we have several options:
{0;?} = select all branches that start with 0
{0;(0,1)} = select all branches that start with 0 and end in either 0 or 1
{0;(0 to 1)} = ......................................... and end in the range 0 to 1.
Conversely, selecting all standard vowels and consonants while disregarding all non-standard character can be achieved with rules as follows:
{?;0}
{(0,1);0}
{(0 to 1);0}
It is also possible to select items from each branch in addition to limiting the selection to specific branches. In this case another rule stated in square brackets needs to be appended:
{0;?}[0 to 2]
The above rule will select the first three vowels from the standard and the non-standard lists.
Basically, rules work in a very consistent way, but there are some syntax conventions you need to know. The first thing to realize is that every individual piece of data in a data-tree can be uniquely and unambiguously identified by a collection of integers. One integer describes its index within the branch and the others are used to identify the branch within the tree. As a result a rule for selection items always looks the same:
{A;B;C;...;Z}[i] where A, B, C, Z and i represent rules.
It's very similar to the Path Mapper syntax except it uses square brackets instead of parenthesis for the index (the Path Mapper will follow suit soon, but that won't be a breaking change). You always have to define the path selector rule in between curly brackets. You can supply any number of rules as long as you separate them with semi-colons.
The index rule is optional, but -when provided- it has to be encased in square brackets after the path selection rule(s).
The following rule notations are allowed:
* Any number of integers in a path
? Any single integer
6 Any specific integer
!6 Anything except a specific integer
(2,6,7) Any one of the specific integers in this group.
!(2,6,7) Anything except one of the integers in this group.
(2 to 20) Any integer in this range (including both 2 and 20).
!(2 to 20) Any integer outside this range.
(0,2,...) Any integer part of this infinite sequence. Sequences have to be at least two integers long, and every subsequent integer has to be bigger than the previous one (sorry, that may be a temporary limitation, don't know yet).
(0,2,...,48) Any integer part of this finite sequence. You can optionally provide a single sequence limit after the three dots.
!(3,5,...) Any integer not part of this infinite sequence. The sequence doesn't extend to the left, only towards the right. So this rule would select the numbers 0, 1, 2, 4, 6, 8, 10, 12 and all remaining even numbers.
!(7,10,21,...,425) Any integer not part of this finite sequence.
Furthermore, it is possible to combine two or more rules using the boolean and/or operators. If you want to select the first five items in every list of a datatree and also the items 7, 12 and 42, then the selection rule would look as follows:
{*}[(0 to 4) or (6,11,41)]
The asterisk allows you to include all branches, no matter what their paths looks like.
It is at present not possible to use the parenthesis to define rule precedence, rules are always evaluated from left to right. It is at present also not possible to use negative integers to identify items from the end of a list.
If you want to know more, join the Webinar on Wednesday!

mers considering extreme sports reject mainstream retailers and like to check out small stores rather of at chains plus malls. Several smaller retailers discuss trends in sports shoe sales. http://skateszone.com/
Though athletic shoes and sports stores and from doorways retailers have reported somewhat uptick in footwear sales due to the increase in extreme sports, the particular beneficiaries inside the trend are independent surf and skate niche stores.
Some West Coast surf and skate shops stated teenagers and even more youthful Generation Xers are not only rejecting traditional sports, but they're also shunning mainstream retailers and malls meant for smaller niche shops transporting hard-to-come-by brands.
Eddie Miyoshi, district manager at Atomic Garage, a 3-store chain situated in Gardena, Calif., stated the soaring recognition of skateboard footwear has boosted the retailer's total footwear business 20-thirty percent this year, rather of '95.
Skate footwear presently represent 80-90 % of Atomic Garage's shoe sales, while couple of years back, Dr. Martens and Timberland drove the retailer's footwear business.
Like many retailers, Miyoshi pointed to Airwalk since the trend's catalyst.
However, if Airwalk broadened its distribution to larger chains, which are frequently located in malls, only a few skate shoe customers adopted. Rather, many youthful males have switched for your skate shops for additional elusive brands like Etnies, Duffs, and Electricity Footwear by Circus. By refusing to market bigger retailers or sports stores, these brands are increasing their cachet among youthful consumers.
"Kids don't want stuff which have been within the shops,In . Miyoshi added.
Searching ahead, Miyoshi forecasted skate shoe sales will remain strong through spring '97 provided "the [hot] vendors don't auction other [non-particularly shop] retailers."
"Skaters and non-skaters are rebelling against mainstream retailers so on to surf and skate shops for many looks," echoed Mark Richards, co-online sources Val Surf, a 3-store chain situated in North Hollywood, Calif. Soaring sales of skate footwear have driven total footwear receipts up 25 percent this year rather of '95.
"The quantity of that increase might be connected while using exposure of maximum games? I am unsure. [Skate footwear] may also be actually the think about the moment,In . Richards acknowledged. And in relation to getting this right look, youthful customers can be very picky.
"Skateboard footwear is a huge category for people, but we're not able to own the brands, Etnies, Duffs, Electricity and Nice, simply because they won't sell us," stated Mark Anderson, buyer at Chick's Sports, a six-store chain in Covina, Calif. "We have people coming every single day requesting them." Consequently, skate footwear have consistently ongoing to obtain about 5 % of Chick's overall footwear business. http://skateszone.com/the-top-8-best-skateboards-for-beginners-reviews-2017/
Nonetheless, some outdoors, niche sports and sports retailers are noting the growing recognition and coverage of maximum sports will receive a modest impact on footwear sales. Trailrunning footwear and approach/outdoors crosstrainers will be the two groups benefiting the very best inside the recognition. Like the skate shoe business, some retailers realize that styling instead of function frequently drives sales of individuals footwear.
"At this time the merchandise is a lot more visual than function," stated Chet James, gm of Super Jock 'N Jill, Dallas, speaking about trailrunning footwear. Still, James noted the current hype over adventure sports helps draw more customer traffic. "The marketing campaigns and media help bring growing figures of people in, nonetheless they frequently occasions day an issue that increases results on their own account,Inch he conceded.
John Wilkinson, executive vp inside the 85-store chain Track 'N Trail, Eldorado Hillsides, Calif., stated the shop has "seen some activity in approach footwear," but he requested the amount of consumers depend in it commercially sport. And, instead of accelerating total footwear business, Wilkinson speculated elevated sales of approach footwear and trailrunners are gnawing away at traditional hiking shoe and boot volume.
But Dan Bazinet, president of Overland Exchanging, a 34-store chain situated in Westford, Mass., believes the company-new looks have breathed existence for the wilting hiking boot category. "[Approach-type footwear] don't represent the lion's participate the hiking market, nonetheless they have elevated the hiking business and provided us extra sales," Bazinet stated.
He designated Timberland's Treeline Series and Rockport's Leadville line as strong performers. Unsurprisingly, he noted the company-new looks are attractive to youthful consumer base than traditional hikers.
For that month of June, sales of men's hikers were up 49 percent at Overland, rather of June '95, while sales of women's hikers were up 17 % for that month. Bazinet also attributed elevated sales that shops walked inside the hiking business, departing that business for that specialists.
Some retailers draw a good example concerning the hiking boom of two yrs ago combined with the current extreme sport phenomenon. "Plenty of bigger chains will get a specific percent in the industry while [extreme] sports remain a fad because they are selling cost-point type gear," described Steven Carre, assistant hard goods buyer at Adventure 16, a six-store chain situated in Hillcrest.
"However individuals [true enthusiasts] will say `we need real gear' and may shown up at us. That will help us after a while. What Size Skateboard good for an 3 4 5 6 7 8 9 10 11 12 13 14 year old

I tell you what I had to do and how I did it.
I have the following situation. A urban context with a square plot 40m x 40m surrounded by buildings.
If I extrude the plot I get 4 surfaces and I need to calculate the minimum daily quantity of direct sunlight hours each test point receives in the period from 22nd of April to 22nd of August. For example for the test point at index 21 of surface with index 1 (I am just creating these numbers in my mind) the minimum is on 27th of April and the test point receive 8 hours (this is also invented for the sake of the example) of direct sunlight. All the other days it receives more. So the values I have to found are these minimums for all the test points. Now how to calculate these minimum quantities is a different issue of the topic of this post and actually I manage it.
Continuing with the explanation of what I had to... so I have only the initial plot that generate 4 surfaces, then I want to test smaller plots generated by an offset of 4 m of the original one, and the relative 4 surfaces for each smaller plot.
So in this case I think I cannot use your suggestion because the object don't exist yet.
I managed creating a loop with Anemone, the loop generate an offset starting from the original at 0 until 4 (then I multiply it by 4 to obtain the offset at 0, 4, 8, 12 and 16. Then I did like you also suggest I record every time the result with the DataRecorder and I create for each result a different branch with the index coming from the loop (0, 1, 2, 3 and 4) with the Flatten component.
In this image you can see all the surfaces saved in the same way as described above and in white the test points that receive minmum or equal than 2.5 hours per day of direct sunlight in the period from from 22nd of April to 22nd of August and in dark gray the test points that receive less.
The main point of this discussion is just the fact that instead use this tricky way I used, or the one you suggest, to analyze separately (because they shade each other) 20 geometries (in this case 20 they could be many more) it would be good if it would be possible just to input all the geometries at the same time and they would not shade each other so to get directly all the results with one run and in a more simple way.
