how to rebuild the geometry topology starting from the mesh.
 
Hi,

I wonder if it is possible using icemcfd to rebuild the geometry topology starting from the mesh. For instance, I have a 3d mesh in plot3d format and I want to extract from it the geometry topology, is it possible to do this in icem cfd or ansys mesher?.

Cheers,

Joel

Mesh to Geometry.
 
Yes.

If it is unstructured, you can use "edit => Mesh to Facets" and get some faceted geometry.

If it is structured mesh (most likely for plot3D), you can convert it directly to Bsplines with the same Edit menu. (Use Import Mesh to load the plot 3D file in the first place). Actually, you can also extract a blocking file from a structured mesh and modify that on your new geometry.

If it is unstructured and you have access to FE Modeler (in ANSYS Workbench), you can "skin it" and convert the skin to a Parasolid (Class A BSplines). This newer tool has much better geometry export capability.
