The model requires several meshes (format can be .ply or .off):
*`mandible`:
* closed surface mesh of the mandible.
* the boundary conditions will be applied in the global cartesian reference frame. Thus, this mesh should be aligned with its principal axes (see MeshLab: Filters / Normals, Curvatures and Orientation / Transform: Align To Principal Axis)
* A gmsh file (.msh) of the volume mesh can also be given
* If this mesh is given as a surface mesh file, it will be meshed with gmsh. Try to mesh it manually in gmsh first because it sometimes fail.
*`teeth`:
* A set of vertices selected on the top of the teeth where contact with the food occurs.
* Using MeshLab:
* Select the vertices using vertex selector ("Select Vertices" button) and the mouse.
* When the selection is finished, invert the selection (pressing "SHIFT-i").
* delete all the selected vertices using "Filters / Selection / "Delete selected vertices".
* check that your model only contains the desired number of vertices.
* save these vertices to a file (e.g. teeth.ply)
*`LTMJ`/`RTMJ`:
* use the same procedure as for the teeth to save 1 vertex representing the left temporomandibular joint (LTMJ) and the right one (RTMJ) to 2 separate files (e.g. LTMJ.ply and RTMJ.ply)
* a series of muscle surfaces (you can name them as you like)
