[ANSYS Meshing] how to mesh this geometry

gus.gkikas · April 1, 2013, 13:46

Hello,

I am working on this attached geometry ,and my goal is to set up an Fluid Flow(cfx) on Workbench,but a I'm having problems with the mesh.

Can you help me with some guidelines and ideas for methods to use?

Thanks in advance

You can find more with the same geometry.

Thanks a lot asal,but I don't know anything about meshing at the ICEM.

I have tried meshing the geometry at Ansys Meshing Application and those are my results

I think,they are very bad...

How can I improve that mesh?

Thanks in advance

Inflation is a must and ofcourse to have fined mesh at inlet and outlet of the airfoil.

Boundary layer as fine as possible for accurate results.

Hi!

You should employ some inflation layer (Prism) around the airfoil. Moreover by using some mesh controls refine the mesh at the rear side of the airfoil to be able to capture the flow in this area.
