, Engineer and Researcher from France with broad programming experience. He is the author of the City in 3D Rhinoceros plugin for creation of buildings according to geojson file and with real elevation. Guillaume already created a new component: "Address to Location". It enables getting latitude and longitude values for the given address:
2) Support of Bathymetry data: automatic creation of underwater (sea/river/lake floor) terrain. This feature is now available through new source_ input of the "Terrain generator" component. Here is an example of terrain of the Loihi underwater volcano, of the coast of Hawaii:
3) A new terrain source has been added: ALOS World 3D 30m. ALOS is a Japanese global terrain data. Gismo "Terrain Generator" component has been using SRTM 30m terrain data, which hasn't been global and was limited to -56 to +60 latitude range. With this addition, it is possible to switch between SRTM and ALOS World 3D 30m models with the use of source_ input.
4) 9 new components have been added:
"Address To Location" - finds latitude and longitude coordinates for the given address.
"XY To Location" - finds latitude and longitude coordinates for the given Rhino XY coordinates. "Location To XY" - vice versa from the previous component: finds Rhino XY coordinates for the given latitude longitude coordinates. "Z To Elevation" - finds elevation for particular Rhino point. "Rhino text to number" - convert numeric text from Rhino to grasshopper number. "Rhino unit to meters" - convert Rhino units to meters. "Deconstruct location" - deconstructs .epw location. "New Component Example" - this component explains how to make a new Gismo component, in case you are interested to make one. We welcome new developers, even if you contribute a single component to Gismo! "Support Gismo" - gives some suggestions on how to make Gismo better, how to improve it and support it.
5) Ladybug "Terrain Generator" component now supports all units, not only Meters. So any Gismo example file which uses this component, can now use Rhino units other than Meters as well. Thank you Antonello Di Nunzio for making this happen!!
Basically just forget about this yellow panel:
This panel is not valid anymore, so just use any unit you want.
6) A number of bugs have been fixed, reported in topics for the last couple of weeks. We would like to thank members in the community who invested their time in testing, finding these bugs and reporting them: Rafat Ahmed, Peter Zatko, Mathieu Venot, Abraham Yezioro, Rafael Alonso. Thank you guys!!! Apologies if we forgot to mention someone.
The version 0.0.2 can be downloaded from here:

obably only using Rhino4, but three people who bought Rhino2, Rhino3 and Rhino4 respectively are three people using one version each.
We certainly don't know how many Grasshopper users there are. Grasshopper installers are not always downloaded via our website or -once downloaded- used multiple times (think class-rooms and company IT). We have no way of knowing whether someone who once downloaded Grasshopper is still using it. That being said, Grasshopper is downloaded ~100 times a day from our website and this number has been fairly constant since 2009 (though slightly on the increase, I'd say ~80 a day in early 2009). There are nearly 96,000 unique email addresses in the Grasshopper mailing list, more than 455,000 in the Rhino4 mailing list.
The size of this community (>17,000 registered users) is a much better indicator of user-base magnitude, but even here we have no idea how many people registered but are now no longer using GH as we do not collect use statistics (yet).

What I figured yesterday is that the increase in radiation because of the reflective facade for the 'worst' month is only about 2-3 kWh/m2 as your looking at a value of 80 without and 82-83 kWh/m2 with reflection.
So my assumption is that the glare factor will play a much bigger role instead of intensity of the sun, looking at comfortable levels. So I'm looking in this as well. It's very cool to play around with these plugins and see the outcome. I'll keep you guys posted.
@ Claudio, that was exactly my problem as well. I presented a direct sunlight hour analysis, to show the increase in direct sunlight hours because of the mirrored facade and at what times of the day the reflections occurred. But it is hard to asses if this is 'bad' or 'good'. The restaurant in question receives more or less 130 direct sunlight hours 'naturally' in the worst month and because of the reflection the result was 161 direct sunlight hours, but the client was like okay..... and is this a problem? So we decided to look at sun intensity but I didn't want to fall into the trap of in the end presenting kWh/m2 and having the same problem not knowing if this is 'comfortable' or 'annoying' etc. Good luck with your study, I'll post my findings
Thanks again guys…
nitions prior to Karamba are to allow the genes to manipulate the form of the shell and then kangaroo to relax the form to its "equilibrium" state.
The definition, as attached, runs fine over one iteration. However, when I run the Galapagos solver, rhino slowly uses up my computers memory and then ultimately crashes (around 80 Galapagos iterations). I don't think that the surface patch, or kangaroo are the issue, as I have run other iterative definitions through them without issue.
I believe Karamba may be occupying memory each iteration that is not released when a new iteration begins. This problem is exasperated by the fact that I am running 11 load cases, 9 of which are point loads defined over each vertex of the mesh. I ran a definition with only one load case, and it reached 170 generations (with a population of 50 for each generation). However, at this point it had occupied 90% of my computer's available memory.
Do you know of a way to ensure that Karamba purges its memory after an iteration, or is this a possible memory leak bug?
Thanks again, any help you can provide is much appreciated.

I think i'm about 80% there. It may not be the most elegant procedure, but it appears to be working. I am having some slight problems.
1. I'm having trouble extracting the edge curve on one side of my mesh
a. I used a mesh plane intersection to trim my site mesh, and the resultant curve extends beyond the limit of my mesh
b. I identified the intersection point, but GH is not shattering on that intersection point. instead it happens at a point further down the polyline
2. I'm can't join my curves. If i bake them, they join into a closed curve.... GH join curves is not behaving. i've had some success joining two segments, but i can seem to get all 4 side wall curves to join.
if anybody could offer some advice, i'd be very appreciative. also, i'd like some recommendations for ways to streamline this definition. I'm sure that there are more creative ways to manage this data, and i'd love to about them. thanks - CSDG

use an attractor curve to adjust curves that are being lofted to create a "wavey" surface. I've attached a picture to show the end result. Right now i create all the curves and then loft them together to create a surface which could then have a rib definition applied to it, and it works, my problem is that this project is for a 80' section of wall with ribs that would be a few inches apart, so that is a ton of curves i have to change everytime i want to adjust the overall shape. So is it possible to have an attractor curve that instead of adjusting the spacing of shapes in plane with the curve, would create high points or low points perpendicular to the curve? Hopefully that makes some sense, i'm having trouble finding the words to explain it, the attached pictures should help.
Any advice on how to do this would be great. I hate being that guy but this project came up last minute and it seemed like something the Grasshopper help save a ton of time in as far as adjustments go.
Thanks,
Kyle

h kangaroo and have found one project that illustrates my idea exactly...
https://vimeo.com/88002087
So far my best attempt has been to use a gridded surface in which the lines of the grid are springs, with a rest length at 80% of their initial length. (call this grid A) This is to simulate as if the material has been stretched 120% of its resting dimensions.
I have been trying to anchor the springs to a secondary grid (Grid B, curves that will be deposited onto the material) at the points of intersection with grid A.
I am not sure if this is the best approach, maybe soapfilm would be better? although i require the boundary (grid B) to adapt also...
Any advice or attempts to explain how Taichi Kuma has done this in his video would be greatly appreciated.
Thanks…
A: Who created it? / Copyright?
B: Anyone have a larger resolution copy of this image (or a vector so I can do a large resize).
Long and short - I'm an artist and I'd like to make a quilt out of that image. I need a decent resolution copy of it so I can do a huge resize and get a 76" x 80" crop out of it. I've tried resizing it in Photoshop, but by the time it's large enough, the quality has dropped below what is usable for my needs.
Thanks in advance! I totally understand I'm relying on the kindness of strangers here. (Also if this is inappropriate to post - please delete. Thank you)

st for the quality of the mesh.
Actually, convergence is much more than simply having low residuals. You can have a wrong solution with very low residuals. Usually, it is a combined process of both run time information on residuals and having an idea or expectation of what the simulation results should be. Another way of assessing convergence is if the residual values have been stable (within a very small limit, e.g. 1E-5) for more than a certain number of iterations (e.g. 1000). We are planning to provide run-time residual plots in Butterfly, hopefully soon. These plots can help keeping an eye on the solution.
You could try as a test if you want to switch to a blend of first and second order (by swapping upwind with linearUpwind in the fvSchemes)
.
Concerning mesh quality there are a number of ways, some of which are a bit advanced for this post and for BF's current capabilities. The best way to start is by refining the background mesh (i.e. the blockMesh). You can do that by assigning more cells to the x, y and z directions in the blockMesh component. However, make sure you increase the max global cells. I would suggest you monitor the output of the blockMesh in order to know the total number of cells there. Your max global cells has to be higher than that for SHM to even work. I'd suggest 2x to start with. Ofc all that requires a bit of trial and error depending on the case at hand.
Hope this helps!
Kind regards,
