Hey there,

Im performing CFD on a deformed geometry, and Im trying to establish a robust workflow. Currently Im in Workbench, and my workflow is this:

1. Static structural: calculation and export .cbd of deformed geometry
2. FE Modeller: create and export parasolid
3. Solidworks: parasolid to dumb solid, create flow domain
4. Design Modeller: share topology/imprint faces etc
5. Mesher: meshing
6. Fluent: run calculation

Currently steps 2 and 3 are problematic. In FE modeller, creating a clean parasolid can be a challenge, and in Solidworks, often the geometry operations fail.

So. I was wondering what everyone else does. Whats your role, what programs do you use, and what is your workflow? What is the easiest, most robust way you have encountered to perform the above steps?

Basically, Im trying to workout whether people in industry have a good way of doing this with no specific software, or use things like geomagic wrap (for example).

Cheers,

David

have you tried using the system coupling tool to couple fluent/CFX and ansys mechanical together?

fluent gives force data to mechanical, mechanical gives displacements in the mesh to fluent. repeats until it reaches convergence.

you could do it by selecting ''coupled'' tools like FLUENT to ANSYS Mechanical. But the question is different from your answer. if ''deformed geometry'' is used in FLUENT again or first time, then you should do something different.I am not sure but you can review some chapters about system coupling or two-way FSI system. One of them seems to appropriate for your question.

Kind Regards,
