Hello Pachyderm Users,

We are going through an exciting period, including the startup of an organization to support the growth of Pachyderm, and extend the educational agenda of the project. In the next few weeks, we will be submitting our long-form 501(c)3 application, which will give us the rights of a not-for-profit organization established in the state of Connecticut. As part of the transition, we are phasing out the old website. The new site will be up in the next few weeks, and you can find it at:

www.orase.org

We are looking forward to the next phase of this project, and we hope that you will be there with us to learn and continue to support us!

kind regards,

Arthur van der Harten

Impulse response (IR) and auralization grasshopper components 1 Reply

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

Comment by Arthur van der Harten on July 13, 2017 at 6:38am: Hi,

There is no limit on the number of surfaces which can be handled, but if any of them cannot generate a render mesh, it may crash.

You will have to trouble shoot your model in order to make sure that none of the geometry is bad.

I don't understand your second question. Could you please explain?

Comment by Stracus on July 13, 2017 at 3:33am: Hi Arthur,

I am using your software for an acoustic simulation. Everything looks working in the grasshopper system but I have two questions.

1. How many surfaces can Pachyderm control in Grasshopper? For now my project is not less then 3800 surfaces and everything is crashing when I am setting a polygon scene.

2. The parameter ED is always overload for the matrix. Is there any secret to solve this problem?

Many thanks

Comment by Sean L on June 7, 2017 at 4:25pm: Hi Arthur,

is there a way to export analyses from simulations in a spreadsheet-friendly (or otherwise parseable) format?

Comment by daviduburke on May 27, 2017 at 6:52am: Arthur,

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 on May 27, 2017 at 2:45am: Hi Arthur,

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

Daniele

Comment by Daniele Rizza on May 18, 2017 at 3:44pm: 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

Daniele

Comment by Arthur van der Harten on May 17, 2017 at 8:41pm: 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?

Arthur

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.

Thank's

Comment by Arthur van der Harten 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.

Comment by Daniele Rizza on May 17, 2017 at 4:50pm: 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?
