The SMESH Module The goal of this module is to create meshes on the basis of geometrical models created or imported into GEOM. It uses a set of meshing algorithms and their corresponding conditions (hypotheses) to compute meshes. In addition, a new mesher can be easily connected to this module by using the existing plugin mechanism. The main functionalities of SMESH are: Visualization of meshes in 3D viewers: Shading, Wireframe Shrink Nodes Special options for mesh (color, lines width, shrink coefficient) Displaying/Erasing of mesh and submeshes Computation of meshes and submeshes on the basis of the following hypotheses: Average length of edges Number of segments Maximal triangle area Maximal tetrahedron or hexahedron volume Computation of meshes and submeshes using the following algorithms: Wire discretization Triangulation (Mefisto 2D) Quadrangle (mapping) Hexahedron (I,j,k) Tetrahedron (Netgen) Group management: Creation of groups of elements Add/Remove elements from a group Remove a group Display/Erase a group Selection of groups Highlighting of groups Information about computed meshes Import/Export: MED UNV Quality controls of meshes: Length of edges Free boundaries Boundaries of multi-connections Area Taper Aspect Ratio 2D & 3D Minimum angle Warp Skew Mesh modifications: Add/Remove (node, edge, triangle, quadrangle) Diagonal inversion Changing orientation Conversion of a group of triangles into quadrangles Conversion of a group of quadrangles into triangles Moving of node Underlying Technologies...
