Coustyx is a high performance acoustic analysis software that combines the Fast Multipole Method (FMM) technology with Boundary Element Methods (BEM) to solve steady state sound fields. Advancements in Coustyx allow users to perform fast acoustic analysis on very large models (1 Million DOFs) over a broad frequency band (low-mid-high).

Take a tour of Coustyx. See our growing collection of Validation Examples and Case Studies. Academic users: our collection of free sample models with accompanying closed form solutions and experimental results is ideal for a course in Acoustics.

We are pleased to announce the release of Coustyx 5.01. This new version includes the Burton Miller Collocation formulation that yields accurate solutions at all frequencies and improved performance. Refer to the release notes for more details.
