Good morning everyone. I’m trying to simulate the acoustic performances of an environment using Pachyderm, both in Rhino and in Grasshopper, but I am not able to find any tutorial about it.
I wrote to Arthur, the man behind Pachyderm, who has been so kind to share with me a couple of GH definitions (one for the study of the sound reflection, the other one to evaluate the acoustic comfort in different points inside a room), but when it comes to modify them according to my needs, I’m lost!
The green element is the pavillon which has inside the sound source (linked to a point), the big red volume around the pavillon is an arena, and both of those elements are linked into the “Grasshopper Geometry” inside the Polygon Scene element.
This is the first problem, because the Polygon scene asks me also for the Rhino Geometry, which wasn’t asked into the Arthur’s example. In addition, I don’t know where to take it, because if I draw a geometry on the canvas and I relate it to multiple elements and/or I internalize it, it becomes a Grasshopper Geometry.
Also, I don’t understand why, when I try to link a surface to the Surface input of Divide Surface, it tell me “Data conversion failed from Brep to Surface”.
Any suggestion? I cannot find any tutorials for this kind of modeling, does anybody have some to share?
I also have troubles with the Pachyderm simulation in Rhino. Once I bake the pavillon and the arena and I set them in meters, then I insert the sound source and the sound receiver, then I assign proper materials to each object in the scene, the results from simulation looks weird to me:
In both cases, the sound source is a geodesic speaker which emits 200W, and the microphone is placed at 50 meters.
More than 150dB?
And the result doesn’t change between the first and the second simulation, but in the first, around the sound source is placed the acoustic pavillon that schould amplify the sound, while in the second one, the speaker is simply placed in the middle of the arena.
I followed step by step the tutorial of Pachyderm for Rhino that you can find on the Pachyderm website.
