Gridgen supports neutral, native, and de facto standard interfaces to CFD solvers (including the specification of solver boundary conditions), grid files, and geometry formats to ensure that Gridgen fits into your CFD process.

Geometry Import

Read more about Gridgen's interoperability in this article.

Geometry on which the grid will be generated (database in Gridgen's vernacular) can be imported from the following file formats.

CATIA V4*
CATIA V5*
Gridgen style wireframe
Gridgen segments/points
Gridgen composite
Gridgen NMB**
IGES
NASTRAN (triangular facets)
PATRAN
PLOT3D wireframe
Pro/E*
STEP*
STL (triangular facets)
UG NX*
VRML 1.0 (triangular facets)

*These file formats are supported in the Native CAD Reader products.
**The NBM file is the interface to the CAPRI CAE Gateway.
