Hello,
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: p 0.1 U 0.2 k 0.2 Epsilon 0.2 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 RW |
Hi RW,
I use simpleFoam too
Hi RW,
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. Cheers, Lam |
Hi Lam,
thank you for your
Hi Lam,
thank you for your answer, I will check out, if this may help me too. greetings RW |
