Mesh inverse volume - wind tunnel

roald · January 11, 2011, 13:36

Hi,

Hopefully someone can help. I am building a wind tunnel to test UAV engines as part of a project. I have created a version of it in soliworks and imported it into ansys workbench using the IGS format.

I am using CFX to simulate my models.

I need to mesh the volume of 'air' conatined within the wind tunnel. It is an open wind tunnel but I have placed caps on either end so i literally want to mesh the volume contained within. There are some complex shapes and turning veins inside etc which i obviously want to preserve also.

If anyone knows how to do this, it would be really really appreciated!

Many thanks!

Parasolid is a better format than igs, especially for complex surfaces.

Your description is a pretty typical simulation. Do the tutorials and things should be clearer. There are lots of pre-processing tutorials on the ANSYS Community website.
