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:
 
 
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,

Use pachyderm for street noise analysis and optimization of planning and building geometry solutions? 7 Replies

Hi - Is Pachyderm only for interior acoustic analysis or can I use it to test impacts of street noise? I am trying to position and shape 3 story residential buildings, with possible insertion of…Continue

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?

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

Hi Arthur,

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

Arthur, 

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

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

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?

Daniele
