NX Flow - Export Results

[rothers]

Is there any way of exporting results from NX Flow 8.5 ? I'm trying to import the results into FieldView.

Tried cgms from both export / simulation / cgms (only seems to export mesh & boundary conditions) and by requesting cgms output in the solver parameters neither of which successfully import into Fieldview.

Hello!,
You can set customer defaults for the output results in the File→Utilities→Customer Defaults dialog box, on the Simulation→NX Thermal/Flow or NX ELECTRONIC SYSTEMS COOLING→Results Options tab:
• Tecplot: Outputs all supported results to Tecplot format.
• Fieldview: Outputs all supported results to Fieldview format.
• CGNS: Outputs velocity, temperature, and pressure results to CGNS format.

Best regards,
Blas.

Thanks BLAS,

Those are the options I was turning on in Solver parameters and the exports are produced. Unfortunately Fieldview doesn't like the NX cgms and it doesn't read techplot at all. I don't have the Fieldview results export option. We're using NX Flow 8.5.1 (Flow not Advanced Flow).

Cheers

To update this I've found if you mesh with tet(4) elements Fieldview can read the NX cgms file and display the results on co-ordinate planes. It can't read results if the mesh is tet(10). I'm still not getting any boundary surfaces (inlet, outlet, walls) coming through though.

Hello!,
NX Thermal/Flow do not take any advanced when using TET10 elements, is better you mesh always with TET4 elements. The governing partial differential equations are discretized using a finite-element based control-volume method. With this method, the governing equations are integrated over a control volume and over a time step. In the element-based finite volume method, the finite volume is defined from elements, this is the reason why the extra midside nodes of TET10 elements are not of interest at all for NX FLOW/Thermal modules.

Best regards,
Blas.

Could anyone out there with NX Flow 8.5 (not advanced) confirm that File / Utilities / Customer Defaults / Simulation / NX Thermal / Flow / Results Options / Optional Output Format / Fieldview as mentioned in the online help actually exists ? All I see are Tecplot & CGNS.
