Hello Foamers,

I hope that you are all well. I am doing a simulations on OpenFoam, specifically C-D nozzle with shroud. I have created the mesh using SnappyHexMesh and setup all required boundary conditions. Now, I am only left with selecting the proper solver for my case. I have run too many cases in simpleFoam, but never dealt with unsteady cases before. My question is which the proper solver for unsteady cases? Can some one share an example in OpenFoam that can handle unsteady problems? I would be really appreciate any help in this subject.

Thanks in advance,

PimpleFoam is appropriate for fully transient (PISO) mode or can be used with large time
steps in a mixed PISO/SIMPLE mode. Take a look at the pitzDaily tutorial for case setup
example.
