Iso Surface for a region
 

Hello. I am simulating a wind tunnel test, and I want to plot some iso surfaces for the low speeds corresponding to the vortex regions.

The problem is that if i create the region Fluent will include also the walls, and I don't want it. How can I tell Fluent to create the surface only in a smaller volume?

Please let me know asap if you know it or if the question is not clear.

Thanks,

Fabio
