CGNS mesh input

D 19 May 2009

The only way to read a mesh file in Typhon is to create a CGNS file.

CGNS format specifications are wide. Typhon can currently "only" handle

only one zone per file
2D or 3D unstructured grid
Tri, Quad, Tetra, Prism, Pyramid, Hexa elements
boundary conditions can be specified through face or node tagging

It is currently impossible to read

multiblock mesh

CGNS files from Ansys/IcemCFD or Ansys/Fluent export have been tested. A collection of CGNS files (tested with TYPHON) is available on our mesh repository.

In main.rpm parameter file, one can specify

BLOCK:MESH

  FORMAT = CGNS

  FILE      = "my_mesh.cgns"

  SCALE   = .001    ! optional scale factor

ENDBLOCK

See mesh import for further details.
