Hi,
I think I have two problems with divergence. One of them is that the solver crashed after a few time steps, but I don't want to discuss this one here. :-) The other problem ist, that the solver solves the case, but the results are not very good. I'm solving with chtMultiRegionSimpleFoam an switched turbulence on. Now I want to see how velocity is solved. By setting the endTime to 100 there is a maximum velocity of about 30m/s. By setting the endTime to 500 there is a maximum velocity of about 200m/s. I have two inlets and two outlets. Inlet is set up with fixed value of u and outlet as zeroGradient. Please note the files added to this post. Maybe someone knows how to solve this problem. Best Regards, tH3f0rC3 |
