I just received similar information from Altair.

The neueste CFD Update is under
ftp://ftp.altair.de/outgoing/hyperwo...80/CFD_Updates

He also noted that there are a few new features:
- automatic prism layer adjustment
- Hex-core meshing
- Load mapper - to map CFD results on to FEA meshes

I hadn't tried it before (we don't have Fluent), but it tried it now and the fluentMeshToFoam seems to work nicely with it.

The STAR-CD export also seems to work better (no more hack with Nastran), but it only writes the STAR-CD version 3 format, which makes the boundary imports take a bit longer in star4.

Hi all,

I'd like to produce a 3D mesh which contains a rotating object (like a fan). I meshed it with HM but I don't know how to set the Zones files which are needed by MRFSimpleFoam. I've tried with the -writeZones options but I think the problem is in the construction of the mesh. Can you help me?

Thanks in advance

Francesco

P.S. I've tested fluentMeshToFoam with other mesh and everything was ok, this is my first mesh with internal objects

Hello Francesco,

I'm not speaking from experience with this, but have you tried the following:
-Creating two different fluid "zones" or collectors in Hypermesh
-Do not connect/equivalence the two zones; this would have to ensure that you have two non-connected zones in your model

Kind regards,

Guido

I have a model in HM with tetramesh on it, and its correspoding tria surface mesh. I want to export this file with mesh 200 for the trias and solid 92 for the 3d mesh. How do I do this? I tried looking into real constants but they don't have solid 92 or mesh 200 as an option. I already added the element types but I don't know how to assign those to my current mesh.

Hi Leonardo,

if you want to import a 3D mesh from HyperMesh in OpenFOAM, please try to export the mesh as a Fluent *.cas file and import this with fluentMeshToFoam in OpenFOAM format.

This should work without any errors

Best regards,
Florian

Hi,
I did what Florian has described above, import 3D mesh from HyperMesh with *.cas Fluent file, then
with the command $ fluent3DMeshToFoam I've created the mesh.
But when I check the mesh whit $ checkMesh I get this message:
...

Can you help me to resolve the problem?
