Dear Korous

I do agree with Dr.Sadegh. We can choose k-epsilon model in fluent too.

Not sure what you mean. Have you tried to read the ANSYS Fluent manual or any fluid dynamics text book, turbulence modeling section? I think it would not be useful, to repeat that here in RG, don't you think so?

Regards,

Dr. Th. Frank.

Add physics > Turbulent Flow, k-ε > determine boundary condition - and material , .... .after run , in results >open 2D plot > add surface > in the expression , type ''ep'' for Turbulent Dissipation Rate (ɛ) , and type ''k'' for Kinetic Energy (k).

You can select the type of fluid regime when you choose the physics you use. In CFD module, single phase flow, turbulent flow and chose the turbulent model you need. You can change the k or epsilon values in setting window of turbulent module.

Dear Korous

Very interesting question! And answers too!

Dear kourosh

I think it can possible to select the type of k-epsilon model in comsol.
