Use pachyderm for street noise analysis and optimization of planning and building geometry solutions? 1 Reply

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,

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).

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.

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?

Hi,

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

I didn't find the .pset file but moving the "For Rhinoceros" folder on the Desktop it works. Thanks.

Comment by Arthur 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.

Hi Arthur.

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?
