3D Finite Elements
Introduction
The 3D Finite Elements object allows the definition of three-dimensional objects in Modalys, using a mesh, which is then converted to modal data with the help of numerical methods. The introduction of finite elements in Modalys is the work of Joël Bensoam after his brillant PHD thesis (2003).
Although the instantiation of the 'finite-element object itself is documented within the Object Reference, this section of the documentation will eventually be expanded to include the family of functions that assist in the creation of these objects.
And last but not least, finite elements are available since v.3.6 in Modalys for Max, very tightly linked to the mlys.lua controller. So we suggest that you take a look at the growing lua Modalys examples within Max. That is a very good starting point.
Abstract Modalys is a sound synthesis software developed at Ircam for research and musical applications. This software allows one to build virtual instruments based on physical models to obtain the most entire range of expressive variations in the instrument in response to intuitive controls. An instrument, as a complex structure, is described by the mechanical/acoustical interaction of its components (strings, tubes, resonators, soundboard,...). Some new research have been done recently to extend the sound prediction to three- dimensional objects with the help of numerical methods. In particular, theoretical and nu- merical treatment of the unilateral and frictionless dynamic contact between two arbitrary elastic bodies was studied and highlighted by simulations implemented in Modalys. This manual presents the new functions dedicated to finite element objects.
