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

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

Try with 200,000 rays, and please post a screenshot of your impulse response. (You will find this on the third tab of the Hybrid method interface).

Comment by Antonio Treglia on January 7, 2017 at 9:35am: The total volume of the stadium is very huge, around 1,5 million mq.
It will be minor than that, because I guess I'llconcentrate on the bleachers and the field, but it remains an high value.

Comment by Arthur van der Harten on January 7, 2017 at 7:20am: Hi Antonio,

For large spaces like that, Ray-tracing programs like that in Pachyderm are the only practical way to simulate sound. Yes it will work, but you will probably need a very large number of rays to adequately sample the space. What amount of volume are we talking about?

I'm starting to learn the plug-in, but before going on, I would ask you if it'll be useful for my project: I'm using acoustic analysis to recover the Rotterdam Stadium, changing it in a multifuncional building. I need to create a model of the stadium in GH to simulate the acoustics for different functions (as concerts, motor ride...), so I could use the results to improve the design and optimize the structure for all of these activities.

By the way, the literature about the acoustics of opened sport facilities is insufficient and I don't know if Pachyderm could help me in this research. Do you know if it works in a building with that dimensions?

Thanks,
Antonio

Comment by Antonio Treglia on December 30, 2016 at 8:58am: I didn't find the .pset file but moving the "For Rhinoceros" folder on the Desktop it works. Thanks.

Comment by Arthur van der Harten on December 30, 2016 at 5:24am: Hi Antonio,

You will need the versions of the grasshopper and rhino plugins to be consistent, as they reference each other.

The .pset file is generated the first time you run Pachyderm for Rhino. Could you please confirm for me that it is there? If so, please delete it (so that Rhino can make its own). Make certain you have installed everything from v2 in your installation folder.

Other than this, maybe your computer has locked the files, and you should go through the properties for each file and hit the 'unblock' button.

Let me know if you have gotten it working or if I can be of further help.

First of all, thanks for release me the plugin. I'm trying to install it on rhino 5, but when I drag the .rhp file it shows me this message:

Error
Access to 'C:\Program Files\For Rhinoceros\Pach_Setting.pset' denied. Impossible load plug-in 'C:\Program FIles\For Rhinoceros\Pachyderm_Acoustic.rhp'

What is the problem? Instead, the plug-in for GH works. Is it a problem if I use Pachyderm v.1 (which works) on Rhino and the v.2 on GH?
