# Mesh import

D 28 mai 2010

Typhon can import

• CGNS files (legacy mesh import, see CGNS import for further details).
• TYPHON internal format from a mesh file (.tym) or a solution (.tys)

In main.rpm parameter file, one can specify

BLOCK:MESH  FORMAT = CGNS or TYPHON  FILE      = "my_mesh.cgns" ENDBLOCK

One can specify some options :

• SCALE = <scale factor> in order to scale all coordinates of the mesh
• coordinates can be modified through a set a symbolic function (see mesh deformation)
MORPH_X = <function of X,Y,Z>
MORPH_Y = <function of X,Y,Z>
MORPH_Z = <function of X,Y,Z>
• SPLIT = ISO-TRI | SVM* for isotropic refinement of triangles or SVM-like splitting (see SVM article). For ISO-TRI, one can apply the refinement recursively with NSPLIT = <n> (default : 1)
