Problem with steadyState solvers using pressure BC
Hi at all,
i have a problem, trying to reach a steadyState for my Case.
It is quite similar to the MultiRegionHeater Tutorial Case.
I fixed the pressure on the Inlet and the Outlet (fixedValue 1e5) and set the Velocity to zeroGradient on the Inlet and Outlet.
I tried different Solvers (rhoSimpleFoam, buoyantSimpleFoam) but always the problem occured, that the pressure Equation could not be solved properly. The residuals rised instead of converging......
Doas anybody know how to handle this?
Perhaps the problem is, that on the other boundaries i don't have a buoyantPressure BC as in the tutorial case!?
Steadystate w/o Meanflow
I do also have a similar Problem,
Global dimensions are (x y z) in mm: (60 1 1). In the center I have a square duct of 5 mm length, which tapers the chanel from h=1mm to H=0.8 mm.
My global resolutions are (141 17 17) cells within refinement near the wall.
solver: any Simple Solver
