Hello, Im computing in Simp
Im computing in SimpleFoam the flowcase of an object in a wind tunnel. The mesh is a structured one and checkMesh tells me its perfect. Im working with the k- Epsilon realizable- turbulence. After running potentialFoam the given flow for the timestep "0" looks great, so my boundary conditions might be ok too.
My problem is, even with upwind- descritisation and turbulence turned off it isn't converging and I have no idea why.
So I set the relaxation factors step by step down to:
but with no effect. Does anyone of you have a clue what could be the problem? Or does anyone had a similar problem and solved it in past?
I would be happy for some hints, thank you
Hi RW, I use simpleFoam too
I use simpleFoam too (turbulence off, but in laminar)
And i have a "better" convergence when I increase the relaxation factors:
U -> 0.8
p -> 0.3
But maybe, we'are not in the same case, because I do not use k-epsilon.
Hi Lam, thank you for your
thank you for your answer, I will check out, if this may help me too.
