This paper introduces MESH2FAUST, a modal physical model generator for the FAUST programming language as well as an open-source framework to design 3D objects and turn them into physical models for sound synthesis. MESH2FAUST can convert any volumetric mesh of a 3D object into a FAUST modal physical model by extracting modal information from the result of a finite element analysis. A wide range of parameters can be configured to specify the material properties of the model, the behavior of the generated model, etc. This system is evaluated by applying it to bell synthesis.
