[ANSYS Meshing] Not able to mesh flow region only surface of body

FredRaw · April 3, 2013, 15:43

Hi guys!

I am quite a rookie at CFD and have a fairly complex problem to solve. Trying to simulate the fluid flow in a static N-mixer.. I have imported the geometry from solidworks into Ansys workbench, specified the mixing element as solid and the enclosing pipe as "fluid", or body surround the mixing element. When I try to mesh the flow path, the mesh is only on the surface of the bodies and not covering the flow path. What have I done wrong, or what am I missing?

Thanks for any suggestions and advice

Regards

Fredrik

Either display cut plane or import mesh to Fluent in-order to see whether the volume is meshed or not.

Thanks for your answer! I´ve used a option called fill, to make a new body for the flow area and specified it as a fluid. Now it seems that I am able to mesh the fluid volume.

Best Regards

Fredrik
