[Commercial meshers] from ICEM to Pointwise

harishameed33 · November 10, 2012, 06:12

hi, i want to export surface grid from ICEM to pointwise.. i am using CGNS format to do this.. but the problem is when i open the file in pointwise it converts my structured grid to unstrutured mesh. i have tried to use other formats but the result is same. i have checkd that its pointwise that diagonalize my surface mesh on import. need help in this regard

Haris:

Try using the PLOT3D format. Pointwise will only keep the quad cells for a truly structured format. Most likely the other formats you are using are writing quad grids, but in an unstructured format.

Also, be aware you can import surface grids either as grid or database. (Or both if you want, but that is two separate operations.)

If that does not work, let me know.

but i only have surface grid in icem... and for plot3d format it says "Solver Plot3d supports multiblock mesh" so how to export surface grid in plot3d format

i have surface mesh in icem and i also want to import it as grid in pointwise not database

It looks like you can select whether you are exporting a 2D or 3D PLOT3D file from ICEM, but I have not used it in years so can't say whether that works for exporting a 3D surface grid.

The format Pointwise is looking for is in Appendix III.1 of the Pointwise User Manual.

Hello,

I can't even read the mesh in Pointwise. I only have the option in ICEM to save as .uns. How can I save in other format?

Regards,
Paul

Paul:

Pointwise can import grids in CGNS format, which ICEM can export, so I would recommend giving that a try.
