Physical Model Languages

Different approaches exist for modeling human tissues, mostly discrete and continuous physical models, e.g. respectively Mass-Spring Networks and Finite Element Method.

Whatever approach is chosen, the modeling scheme always follows the same pattern from the generation of the 3D geometry to the analysis of the simulation results. However there are no generic tools that allow for designing a physical model independently from the approach.

This yields to the development of specific tools that are not reusable and that do not facilitate the comparison between methods.

Two physical model languages have been designed using a highly customizable framework that takes into account every steps of the modeling process, and thus can be used for any type of approach. We define two extensible languages :


 * PML to represent both continuous and discrete physical models
 * LML to define constraints and loads to be applied during simulation
