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.
quadtotri2 quad to 2 triangles, no new
points.
prismtotet3 prism to 3 tets, no new points.
quattotri4 quad to 4 triangles, with one new
point.
pyrtotet4 pyramid to 4 tets, with one new point.
hextotet5 hex to 5 tets, no new points.
hextotet6 hex to 6 tets, no new points.
prismtotet14 prism to 14 tets, four new points (1
+ 3
faces).
prismtotet18 prism to 18 tets, six new points (1 +
5 faces).
hextotet24 hex to 24 tets, seven new points (1 + 6
faces).
tree_to_fe quadtree or
octree grid to grid with no parent-type elements.
[ cmo_snk / cmo_src ] :
are 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.
