e and i get it. If you have time check the attached papers we published a while ago in relation to the contribution of thermal mass in the reduction of temperature in residential buildings. See the nice contribution of the heavy TM or the lower one for light TM.
As for the solarHeatCapacity, your description (of the 50W) is derived on a 1 Facade/Floor ratio and fully glazed. The only way to reduce it is to increase the ratio (bigger facade area). Which is not recommended (energy losses), but this is a different issue. So, roughly, we can say that 50 is the lower value. If i have less glazing area this number will be higher (right?)
I want to define a value list of "architectural situations", so it is easy to explain and understand. One situation can be:
"Ratio facade/floor 1 & Fully glazed" = 50
"Ratio facade/floor 1 & Half glazed" = 75
"Ratio facade/floor 1.5 & Fully glazed" = 30
"Ratio facade/floor 1.5 & Half glazed" = 50
"Ratio facade/floor 0.75 & Fully glazed" = 70
"Ratio facade/floor 0.75 & Half glazed" = 90
Makes sense for you something like this?
I also defined a value list for the timeConstant like this:
Light Building (Mobile home) = 1Medium-light building (Cement tiles on floor) = 4Semi Heavy Building (Concrete floor + Tiles) = 8Heavy Building (Concrete floors/ceilings + Heavy external and internal walls) = 12
As for the first 5-10 cm effective TM in general my assumption is that you take half of the mass to your space and half to the space above/below you. Will be interesting to do a parametric study on just the thermal mass, uninsulated and insulated to see what the depth limits effectivity will be. Interested in doing such a study together? Can be a nice work even for publishing.
Thanks a lot ... again,

sent a 3D shape without any ambiguity. If the shape you're trying to convey falls outside the scope of existing standards, then it can't be done, but this is a problem of standards, not an intrinsic shortcoming of pencils.
[...] with the computer theoretically acting as a decision maker.
The computer makes no decisions on it's own. It's a fully deterministic machine, meaning that any output is the result of applying a set of rules to some pre-existing data. Humans make the rules. At no point can you blame the computer for coming up with a bad answer, it's always some human who is responsible.
[...] it seems to often be split between Computerization, and Computation.
I'm willing to concede there exist cases that are unambiguously one or the other, but there's a gradient in between these two extremes, they are not separate categories. If I draw a box by specifying the 8 corner points as XYZ coordinates then computation can be said not to be involved. If I draw a box by specifying 2 opposite corners then the computer has to compute the other 6 coordinates and we're already on our way towards the other extreme. If I draw a box by specifying a width, height and a required volume, more computation is needed. If I specify a box by a width, a volume and the requirement is doesn't cast too much shadow on some other shape, more computation is needed. At what point do we say "now it qualifies as computation/solving"?

LaN FLIGHT is looking for highly ambitious-adaptable-endurance oriented participants to fully embrace the nature of this curated experience. Please take a look at our 3 previous editions to best judge if this type of experience suits you. If you are willing to allot 8 days of your life to this pursuit and have no allergies to extreme mobility & group dynamics… welcome to LaN FLIGHT.…
mport the geometry again.
Right?
How about this? I add an extra object called something like "Geometry Cache". You have to give it a unique name. If you plug geometry data into the left side of this component, it will bake all that geometry and attach UserStrings to all those objects like "<name>: {0;0;3}(8)" where <name> would be your name and the rest is the exact location of that piece of geometry in a DataTree. It should probably also delete any objects already in the 3dm file that have that custom name/data assigned to them.
If you don't plug any wires into the left side, it will instead search the 3dm file for all geometry with the appropriate user data, load them into a correct DataTree and supply that data to whoever plugs into the right side.
If you plug wires in both ends, it will just function as a generic Geometry Parameter.
It might be tricky to write a good event handler for this thing, maybe I'll just restrict myself to an UPDATE NOW! button on the object itself, so you can trigger an update manually.
ps. benefit of this approach is that everyone can create and harvest geometry with such user text, whether they use Grasshopper or not.

And got the same result as you did. Suddenly the definition started working. Although I got this error message when I opened the compression tension null.gh file:
Message log start (chronological): --------------------------------------------------------------------------------Plugin version: 0.8.0066 Input parameter chunk is missing. Archive is corrupt. Output parameter chunk is missing. Archive is corrupt. Output parameter chunk is missing. Archive is corrupt. Output parameter chunk is missing. Archive is corrupt.
Why is that?
Can I dare to ask you few more questions?
2) I want all of my members to be made of solid (not hollow) circular cross-sections.
Does that mean that my diameter and thickness need to have the same values? Like this:
?
3) I have wind load from 8 directions. Is there a way in Karamba to create load groups and choose the one with the most extreme values (group that will be used as the most relevant one for dimensioning)?
Thank you.…
are just the 8 cases, so you're actually doing it right here (scroll down on this page, and you'll see a separate subset all about marching tetrahedrons http://paulbourke.net/geometry/polygonise/). The benefit to using marching tetrahedrons is exactly this: that the number of possible "cuts" through the tetrahedron are dramatically smaller in number than those through a cube.
However, I have found that also what you're seeing that the linear interpolation creates some odd distortions (which is why I went ahead and later did the marching cubes implementation). Some of this comes from the density of the sampling grid: the more dense, the fewer distortions.
What I would suggest, if you want a (relatively) quick way to improve this outcome:
1) build up a full mesh rather that bunch of surfaces, and use Rhinocommon to combine identical vertices, and rebuild the vertex normals
2) run a couple rounds of laplacian smoothing on the mesh to better distribute your vertices (for each vertex, make it equal in location to the average of its neighbours)
3) create a line normal to each vertex roughly the length of your sampling grid and test the endpoints of it against your scalar field formula, and then do one final linear interpolation between those two points for your vertex.
This should give you a smoother mesh for sure.
But good work getting this far! …

I kept adding new text every day until now... and now I have to change almost all the text I did type but... it's made of curves!
So I was wondering if anyone has ever had similar problems solved by a gh definition
In case no-one has ever had similar troubles (I think you all here are smarter than me :P) how would you proceed to create a similar definition, given all the text has same dimension and font?
I would:
a) create a set with all the possible character-curve in that Font b) create an identical set with the same characters as type
c) compare this set with every given text-curve in the drawing (issue: the number 8 is made of 3 different curve .___. same as letter B... A has 2, as D, R, O, P, p and so on...)
d) list item from set 'b' using pattern I get from 'c'
e) evenctually -this is a moonshot in the moonshot- concatenate characters at 'd' based on proximity of different character-curves (to get "ABC" as a whole text, instead of "A" "B" and "C" as separate instances)
It sounds kind of challenging!
...maybe I'm better start re-writing text NOW as it could EASILY take me a couple of days to get things done... :)…
g commands. In addition, this workshop will give students a functional understanding of Grasshopper and Parametric design; this will allow them to build on this understanding into more advanced projects of their own. The class also covers information on fabrication techniques with RP or laser machines and optimization and fabrication using RhinoCAM for CNC machines.

s is like flattening your data PARTIALLY - chopping an index off the end of the branch paths without obliterating the tree entirely. When working with one "set" of input data, a flatten works to get these lists to match up - but when working with multiple sets, we need to be careful to preserve the original branch indices that keep all four of your original regions separate. As a rule, whenever you're feeding two data trees into any component, they should have the same number of branches. (or one should have branches and the other should be a flat list, in other cases).
The rule of thumb I tend to teach is this:
In 90% of cases...
For lists, all your inputs should either have 1 item or N items. That is to say, if you're feeding 4 items into one input and 9 items into another, something is probably wrong.
For trees, all your inputs should have either 1 branch or M branches. That is to say, if you're feeding a tree w/ branches {0;0} to {0;3} into one input, and a tree w branches {0;0;0} to {0;3;8} into the other input, something is probably wrong.
Grasshopper essentially matches up branches first, then lists second. By "matching" I mean it processes them together. Simple example of the Line component - it will match the first branch of points in the A input to the first branch of points in the B input, creating lines between those points, then match the second branches, the third branches, etc. THEN, it applies the same logic to the level of the list (with a pair of matched branches {0;2}, match all the items in those branches to each other - first item in one branch to the first item in the other branch, etc.)
This is a tricky concept but it seems like you're already well on your way to understanding it from your definition - "PShift" is a critical tool in your path management arsenal. I hope this (overly long) response helps clear things up for you!
