====== GMSH ====== [[http://geuz.org/gmsh/|GMSH]] is a a three-dimensional finite element mesh generator developed by Christophe Geuzaine and Jean-François Remacle. For a given contour, GMSH can be used to generate an unstructured mesh of the footprint, based on triangular elements. This footprint can then be extruded using [[:mesh:extrudemesh|ExtrudeMesh]]. An example of mesh generation is proposed for the Tête Rousse application of [[:courses|Elmer/Ice course]]. Mesh refinement can be improved using the [[:mesh:yams|YAMS tool]]. To convert to Elmer-grid format, use for example ''Elmergrid 14 2 mesh.msh -autoclean -order 1.0 0.1 0.01''.
