  • Very cool, but Error "Index was outside the bounds of the array."

    Hi, I am intrigued by Pachyderm. Thanks for creating and sharing it. Oddly, I am experimenting with not a room but a portable semi-transmission-line speaker enclosure. I want to see what's going on in it. The Pachyderm case is pretty much a boilerplate tutorial thing, largely copied from…

  • Why does the calculated Definition (D50) in my simulation report show as NaN?

    D50 is defined as the ratio between the acoustic energy arriving within the first 50 ms (including the direct sound and early reflections) and the total acoustic energy of the entire impulse response at the receiver position. Therefore, it is possible that the total acoustic energy is zero or not…

  • Issues running Pachyderm on Rhino 8.(Crashing)

    Hi Arthur and everyone.First of all I would like to give my thanks for such amazing initiative.I'm having issues running Pachyderm on Rhino..I have installed Pachyderm 2.6.0.17 using PackageManager.I'm using Rhinoceros Version 8 SR18 (8.18.25100.11001, 2025-04-10)Currently running in .NET Framework…

  • Sound Simulation_ Reverberation Time calculation_Inconsistant Results

    Good morning all,I am currently working on the calculation of the reverberation time of different closed spaces. I have a closed geometry (simplified model of the Hypogeum in Malta), and what I did was change the scale of it, so I had 3 versiones in: 1:1 / 1:2 / 1:5. What caught my attention was…

  • Could not load file or assembly 'Pachyderm_Acoustic, Version=2.6.0.14.

    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 Grasshopper I receive a series of errors, and it's impossible to run any simulations. I tried uninstalling…

  • Impulse response (IR) and auralization grasshopper components

    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 (exported a mono and ambisonics IR as .wav file, and Auralized it with an anhechoic .wav through the…

  • Running Simulation...

    I tried numerous times to conduct a simulation for a simple case study with one receiver and one source, but it took a long time each time, that can reach 20 hours and may not complete the simulation, although, I used several computers with varying specs. How can I solve this problem and shorten…

  • Software capabilities

    Hi!This is very interesting, but I have some questions about the applicability / limitations of your software. What it can and what it can not do. I am an architect, used to formfinding but am not acoustically trained in any way.I want to optimize the shape of a sound protective fence next to a…

  • Actual reverberation time and error from Pachyderm simulation

    Hi all,I'm currently working on calculating reverberation time using Pachyderm Acoustics.I have a reverberation chamber close to me, and I have an environment where I can check the actual reverberation time.The reverberation chamber of the attached GH file was given a condition of low sound…

  • Pachyderm does not load

    Hi, I loaded Pachyderm into Rino 7 and tried a simple model in a box and it immediately crashed Rhino. I cycled through that a few times with the same result. I off loaded Rhino 7 and re-loaded Pachyderm to no avail. I then purchased Rhino 8 and cycled through the same problem. Now Pachyderm will…
