Moving mesh forces on patches and turbulence solver

jackdaniels83 · May 31, 2007, 09:38

Hello,

I hope someone can give me some hints on that:

I am new to OpenFOAM, C++ and Linux and i need a solver that solves forces on selected patches in y-direction, uses a turbulence model and provides moving mesh. Has one done something like that?

If not, what solvers do i have to combine to get it.

I need it for my final year project at the university, where i have to calculate hydraulic valves for a company that is supplier for the automobile industrie.

Any help is welcome, thanks!

Hi Daniel,

do you need moving mesh with or without topological changes?
if you need only moving mesh without topological changes, you can combine icoDyMFoam with turbFoam and you will get what you need. Then you need to write a dynamicFvMesh class accounting for the mesh motion of your case.

Thanks Tommaso,

I don't need topo changes, it is only a linear moving cock.

But what is about the forces? I need the forces resulting from the oil flow that appear in the moving direction on the cock.
