I currently still have GAMG, but I switched to pimplefoam which added some stability. The 'outflow' BC in fluent works brilliantly. That's the only difference I see, so I am trying to fix my outlet...

Still no luck

FLUENT converges completely fine, but OpenFOAM blows up. Completely lost on what BC to implement....Anyone out there have any suggestions?

Msu,

Thank's for the advice. I will try that. The checkMesh shows some highly skewed cells, but the ICEM output doesn't. The min Orthagonal quality (in ICEM is 0.3), and the min Skew (in ICEM is...

Update

I am starting to wonder if my mesh was somehow improperly converted from a fluent3d mesh to an openfoam mesh. I can't find any problems with my boundary conditions, and if I use the same mesh in...

I reduced those to 2, but it didn't improve the situation. I also reduced the timestep, and it didn't help either. Might I send you my boundary dictionaries? Ithink I may have accidentally set a...

HI msu,

I tried implementing the new scheme as you suggested; however it looks like the solution is still unstable. I was flirting with Co = 0,5, so I am going to lower the timestep by an order of...

I have implemented that scheme. I will update you and let you know how it goes. DO you think upwinding this term will cause too much numerical dissipation?

pisoFoam - unstable pressure residual

I am looking to get some help figuring out why my pressure residual keeps rising. I am conducting an LES simulation; the mesh is pretty good quality (pure hexahedral), and mesh and boundary...
