[ANSYS Meshing] Use solid body of influence while suppressing mesh

brian_troyer · March 1, 2020, 21:53

I am a new user of Ansys CFX version 20.* I would like to simulate a flow around a solid.* I am not interested in wasting mesh on the solid itself, but I would like to use the solid to influence the mesh in the surrounding fluid domain (through body of influence or sphere of influence, etc.).* This strikes me as something which should be simple, but I have not yet found the answer.
*
Another possibility, can I affect the mesh of the surrounding fluid domain by face meshing the solid, without meshing the interior of the solid?

Thanks, and sorry for such a newbie question!

You can either refine a curve, surface or volume depending on what you want to achieve. I think all that should be well covered in tutorials by ANSYS and other resources (youtube, ...). Did you have a look at these?

Like that? https://www.youtube.com/watch?v=QVfJiydCu2g
