Well I've tried more schemes, but to no avail. Does anyone have any idea what else could be wrong here? I have read in many other threads that the mesh caused problems, so I'm now taking a close look...

The intermediate schemes didn't work with the non-smooth solvers. However, I'm now trying smooth solvers for U, k, and omega as you suggested, with linearUpwind. Let's see what happens...

Replies: 7 simpleFoam: case only converges with most div schemes set to upwind Views: 2,854 Posted By buffi simpleFoam: case only converges with most div schemes set to upwind Hi, I have a case here (several similar cases, in fact) that I want to solve with simpleFoam, but it only converges with div schemes set to Gauss upwind. The only execption to this is...
