A widely used open source acoustics simulation software, for use with the Rhinoceros and Grashopper design software
An open source collection of numerical and geometrical simulation techniques curated by Open Research in Acoustical Science and Education. As of the time of publication, Pachyderm includes geometrical acoustics (ray-tracing and image source with enhancements, and visualization), Finite Volume Method (with several built-in applications, including eigen-frequencies, 3d scattering coefficient prediction, and visualization), and Transfer Matrix techniques for calculation of acoustic absorption which can be applied in the simulation techniques. The software is provided as a growing public resource for professionals and researchers alike.
The software can be downloaded from the ORASE web site.
