Description
|
|
Reads .msh format generated by the Adventure system.
|
|
|
|
Note: the .msh format does not contain any boundary information. It is
|
|
purely a description of the internal mesh.
|
|
|
|
Can read both linear-tet format (i.e. 4 verts per tet) and linear-hex
|
|
format (8 verts per hex) (if provided with the -hex option)
|
|
(Note: will bomb out if not supplied with the correct option for the
|
|
file format)
|
|
|
|
Not extensively tested.
