Hi!This is very interesting, but I have some questions about the applicability / limitations of your software. What it can and what it can not do. I am an architect, used to formfinding but am not…Continue

Pachyderm incorporates auralization (the rendering audible of a simulated room). Please feel free to share your creations here, and/or ask questions.Continue

Materials Designer

Pachyderm incorporates a Materials designer which uses a transfer matrix system to calculate the absorption of a given finish material assembly. Feel free to ask questions about this here.Continue

I made it through my Thesis project. Thank you for all your help and for creating this tool! You are saving the world...

Comment by Daniele Rizza yesterday

Hi Arthur,

Do you have any GH acoustics file that I can study to learn to use parametric pachyderm?
Thank you

Hi Arthur,
I have the last version of Rhinoceros and Pachyderm so this is not the problem. Maybe my libraries are blocked but I don't know how I can unlock it.
This evening I tried to start the analysis in a simple cubic room and the "calculation solution" started. Maybe my last model was too complicated. It is possibile? 
I'll write you as soon as try to remodel the new room.
Thank you

Hi Jose,

I don't recommend using the software in 32-bit. There are too many features for which the memory limitation would make it impossible to complete a simulation...

It is very unusual to need that these days though. Why do you need 32-bit?


Comment by Jose Giraldo on May 17, 2017 at 8:30pm

Hi Arthur, Do you have an installer for a 32-bit version? I've the same issue of Daniele.


Comment by Arthur on May 17, 2017 at 8:09pm

Hi Daniele,

That sounds like you are either using a very old version, or libraries are blocked.

First make sure you have the latest:

Let me know if this solves your issue.

Hi Arthur,

I'm working on a model of multifunctional room but I have a problem with Pachyderm. 

I have modelling the room and assign the acoustical proprieties of the materials in "Pachyderm Hybrid Models" but when i try to start the "calculation solution" Pachyderm stop working and Rhinoceros shuts off.
Can you help me please?

Hi Arthur,

Could I get the example file for Pachyderm? Because your website is down and the dropbox link is dead. Thanks before

Hi Antonio,
Try the Pachyderm_Mapping command. If you execute the stimulation in there, you can get an area map of the parameters.

The grasshopper component communicates with the Rhinoceros plugin. You did have received an example file with the grasshopper component.

Comment by Antonio Treglia on February 21, 2017 at 6:35am

Hi Arthur,

I'm still working on the model of the stadium, with acceptable results. I would like to know if with Pachyderm I can get graphs of the analyzed parameters (T30, EDT, SPL...)  or I can see just the energy/pressure curves and the values of the other parameters.

Then, Pachyderm for GH is linked to the Rhino analysis? Or are they indipendent? I don't understand how to use the plug-in in Grasshopper...
Thanks for the availability.
