Cannot convert fluent or tgrid hexcore mesh
 

Hey all,

I typically export ANSA meshes to FOAM directly but in this case I want to convert a fluent hexcore case. It was generated in tgrid and converted to polyhedra and then sent to fluent. The mesh has tets and prisms, and all the wall cells are tria. I was able to convert pure tet meshes and tet+prism meshes, so I have narrowed it down to the hexcore being the issue.

I have tried the following:

Wrote out tgrid mesh as polyhedra to .msh
Wrote out tgrid mesh NOT as polyhedra to .msh
Wrote out tgrid mesh as polyhedra to .cas
Wrote out tgrid mesh NOT as polyhedra to .cas

Using fluent3DMeshToFoam as suggested here I got the following error: http://www.cfd-online.com/Forums/ope...al-meshes.html

When I do this with fluentmeshtofoam (also on the four tgrid exports listed above) I get the following error:

When you export to fluent there is only one option, unlike the 4 from tgrid. You can only export polyhedra and only to .cas format. Using fluent3DMeshToFoam I get:

And using fluentMeshToFoam I get:

Hi Robert,

I have no answer for the mesh conversion, just a question.
Why don't you just mesh in ANSA the volume using
MESHV>Hexapoly algorithm and output in OF directly
as you have done before?

Well, I am converting an old mesh for a project where I no longer have the geometry to do a new mesh for.

BUT, I have figured out the problem! FOAM didn't like my boundary condition names! Some of them had a slash in them "a_domain/symmetry"

Once I change the slash to an underscore it worked (so I think, we'll see when I solve it haha!)
