Default surface mesh translation
Posts: n/a
I have a surface mesh defined as a list of triangle vertices coordinates, and then connectivity of the triangles. That is: coordinates: x1, y1, z1 x2, y2, z2 ... vertices making each triangle: corner1,1 corner1,2 corner1,3 corner2,1 corner2,2 corner2,3 ...

I need some suggestions regarding importing this triangular surface geometry into CFX Build 4 or 5. (Maybe generation of an iges file from the data.)

Also, does anyone know of a good reference that reviews the various 3d solid model formats.

Thanks so much for any and all responses.

I suggest looking up the Patran Neutral mesh format or CGNS mesh format. Alternatively, you could use the API's supplied with CFX-5 to import your own custom format.

For the Patran Neutral file format, download the PCL documentation from the CFX Community site (it is not part of the regular distribution). The mesh import API's are included in the standard installation and fully documented.

Regards, Robin

If you've only got 2D elements you might try translating your data to Patran Neutral file format as nodes and 2D elements, importing the data and then using the Create>Surface>Mesh option to generate geometric surfaces from them. You could then use these surfaces to generate a B-rep solid and generate a volume mesh in CFX-5 from there.

The CFX-4 and CFX-5 documentation should give you the details of the neutral file format.
