GRID2GRID

The grid2grid command converts a mesh with one element type to a mesh with another. The conversion type is determined by the second argument.

FORMAT:

grid2grid / ioption / [cmo_sink] / [cmo_source]

ioption: is a character string that determines the element type of the source and sink meshes. There is no ‘default’ option - this argument must be specified.

[ cmo_snk / cmo_src ] : the mesh_object names.

cmo_src is the original grid.

cmo_snk is the name for the new tet or triangle grid. These may be the same grid, if so desired. If both are left blank, the current mesh object will be used. If only one mesh name is given, it will be used at the sink mesh, and the current mesh object will be used as the source.

EXAMPLES:

grid2grid / hextotet24 /  cmo_tet / cmo_hex
Convert each hex element in cmo_hex to 24 tets and name the new grid cmo_tet.

grid2grid / quadtotri4 /  new_mesh
No source mesh is given, so the current mesh object (which is a quad mesh) will have every quad converted into 4 triangles, and saved as new_mesh.

grid2grid / tree_to_fe / new_mesh /  octree_mesh
Every element in octree_mesh will be scanned to see if it is a parent element. If it is, it will be removed, so only the leaf elements remain. The result will be stored in new_mesh.
