Turbulent flow in a duct
 
Good day Everyone,

I'm new to OpenFoam, and I would like to get some help for a case I'm trying to simulate.

I have a rectangular duct, in which I would like to simulate an incompressible steady-state turbulent flow, using regular k-epsilon method.

My first question is what solver is the most suitable for this case?
Is it simpleFoam?

My second question concerns "adjointShapeOptimizationFoam": what do "Ua" and "Pa" physically mean?

Thank you for your help and understanding.

I tried with simpleFoam, and I have some problems with the calculation.

Here is the link with files concerning my case, I'll be grateful for any help I will get.

I uploaded : checkMesh.log file, calcul.log file, fvschemes and fvsolutions files, as well as the compressed case entirely.



Thank you very much for your understanding, and I hope you will not be severe with me I'm just a student.

simplefoam has worked for me for incompressible.
rhosimplecfoam for compressible
both with K-Omega turbulence modeling
