About libAcoustics library

To the contents

The libAcoustics - library for far-field noise computation. At current time contains 3 kind of far-field prediction models:

  1. Curle analogy

    Based on equation 3.3 from Curle N. (1955)

  2. Ffowcs Williams Hawkings analogy

  3. CFD-BEM coupling

Tutorials and examples

To the contents

The libAcoustics source code tutorial, which was prepared in Chalmers University

Some examples are presented in the conference paper Epikhin A.(2021)

libAcoustics library Wiki (in progress)

Available versions of the library

To the contents

We currently support the library for the OpenFOAM+ versions. Current Release

The library is available for next OpenFOAM versions:

Note: Please use the v2112 or later versions because we fixed some important bugs in them that had been present in earlier implementations.
