Dear Samuele, vmtk can - remesh a surface triangulation (i.e. generate a surface triangulation with good quality and with a desired local element size starting from a general low-quality mesh). The algorithm here is an heuristic algorithm I wrote based on edge flipping, splitting and collapsing, see this paper for a few details: Antiga L, Piccinelli M, Botti L, Ene-Iordache B, Remuzzi A and Steinman DA. An image-based modeling framework for patient-specific computational hemodynamics. Medical and Biological Engineering and Computing, 46: 1097-1112, Nov 2008. - generate prismatic boundary layers (this part of the code works for now for thin boundary layers, but we'll extend it in the near future). The algorithm is just based on the projection of the surface along the inwards normals. - generate a tetrahedral mesh of the interior (for this latter functionality vmtk internally relies on Tetgen). See http://tetgen.berlios.de/ for details on the algorithm. Hope this gives you a start
