Hi,

I am working on adjoint optimisation for one of my Master projects but I am having problems exporting the resulting geometry to any CAD package. I have taken a look to the Fluent User Guide but there are not any comments on this.

I know that the RBF Morph add-on allowed to save morphed geometries to an STEP file but I don't know why this option is not available for my version (16.1) under Define->Mesh Morpher/Optimizer.

I have tried the methods described in http://www.cfd-online.com/Forums/ans...uent-mesh.html and http://www.padtinc.com/blog/the-focu...sh-to-geometry but still no luck.

Report:

-The FEModeler method takes ages for a 700k cells model so for bigger ones it would not be feasible.
-Mesh is unstructured so the Structured to CAD faces command in ICEM CFD wouldn't work.
-I was able to create a STL in ICEM by using the Mesh to Facets commands and exporting the geometry. The problem is that the faceted CAD has too many faces and software like SolidWorks cannot handle it.

I would like to find a way to convert the resulting mesh to a surface-based CAD format (IGES/STEP) that can be easily modified using a CAD package. Any ideas to do this?

Thank you.
