algorithmic modeling for Rhino
Hi Arthur,I'm experiencing a persistent issue with the Pachyderm components in Grasshopper. While the plugin works correctly when launching a simulation directly from Rhino, as soon as I open…Continue

Hi Arthur,Thank you for your software as usual, it is a great tool !I tried my model using the Pachyderm Rhino interface to auralize and export some impulse responses, and it works like a charm…Continue

Hello,
I am trying to do some mapping calculations, but every time I start a calculatoin (Settings: Specific Ray Count, default settings), receiver displacement: Audience) Rhino crushes.
I've tried this in Rhino 6 and Rhino 7, but it keeps crushing. Is there something I am missing? Thanks for your help!
Hi Konsta,
I think I need more information. Would you mind emailing me a detailed explanation of the issue you are dealing with?
Info@orase.org
Thanks,

Hi, unfortunately none of the two links to the website work. Both links are broken or lead me to a page with a password protection.
Hi Sebastian,
If your model is very complicated, this may be the reason. Occasionally, Rhino encounters a piece of geometry that can't generate a mesh, and then it fails pachyderm. I've tried to catch some of these cases, but some still elude us.
I can help you troubleshoot the model if you like. Can you send me the file to info@orase.org?

Hello Arthur,
I'm trying to do a calculation inside a small chamber music hall (~490sqm). After applying a material to every surface and preparing everything (as told in this tutorial https://vimeo.com/247018860) I click on Calculate Solution and the button grays out and the message "Solution exception:Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index" appears and I can't try again until restarting Rhino. I know this has happened before but I can't find a solution. I have a fairly complex geometry with reflective panels hanging from the ceiling, I don't know if it may be affecting. Thank you in advance.
Hi again Arthur,
Thank for replying, my bad indeed that material coefficient was able to assign data just fine as you mentioned.
I am facing a different problem atm,
Trying to use SurfaceSource, every time I assign a surface as a source Pachyderm won't run the calculations (hybrid model>impulse>calculate solution). The same 3D model will run the calculation with the other sources (dodecahedron, speaking person)
I am a) inserting SurfaceSource b) selecting a source surface c) choosing SPL for every 62.5/.../8000Hz, and I do get the dodecahedron speaker icon over the selected surface. When I hit calculate solution nothing is happening no msg in the command line.
Also when I am in Rhino environment Properties (Rhino Properties>Sound Source Control) when selecting the Surface source the octave/SWL/SPL is not present, at the same time if I choose a different source the chart will present.
Thank you in advance
Hi Petros,
I just tested both of those systems, and they seem to be working fine (both openings of .pac1 files, and custom absorption coefficients). However, if you have found something I can't reproduce, the best thing you could do is send me the .pac1 file, so that I can look into it.
Regarding the absorption coefficients, try again. I'm very certain that system works fine.

Hi Surakist,
Sorry for the long wait. I didn't get a notice that you had posted... Happens sometimes.
First off, what pachyderm is doing is very computationally intensive, so unless the window outright disappears, it has not crashed. You should just wait for it to complete what it is doing.
Second, it is likely that you are using very low absorption coefficients. You should reconsider whether those coefficients are the right ones. There are few places on earth that have that much reverberation.
Let me know if you have additonal questions.
Arthur
