2D Finite Element Analysis for Acoustics
Wavefront is a programme for simulating 2D acoustic systems, with a particular emphasis on determining wavefront shapes at the mouths of horns. It accepts CAD drawings in DXF format and produces animated displays of wave propagation as well as exporting various data as text files. It is GPL software and runns on Linux and Windows.
