ICEM / FLUENT : mirroring mesh

philus · January 7, 2015, 04:53

Hi all,

I have to simulate an asymmetric flow into a symmetric geometry. I have then created the mesh (with ICEM, a structured mesh) for the half of the geometry and I have now to mirror it in order to use the whole geometry. My questions are:

- is it better to do that in FLUENT or in ICEM?

- how to do that?

I know how mirror a mesh in ICEM but I don't know if doing that it is able to links and connect correctly the nodes at the interface. Maybe I have to do some supplementary operation?
Also I don't want mirror separately the geometry and then the blocking because I should modify all the edges bunching in the mirrored part.

Thanks in advance

Ok, nobody answers.

Finally I decided to mirror the computed mesh in ICEM. Doing that you have the possibility to choose the option "merge nodes" and "delete duplicate elements" and apparently it works well. I also used this as reference.

Cheers
