If the longer simulation runs OK then it is likely to be something wrong with your setup of the shorter one. If you also changed the inlet BC type between runs then that is likely to be the problem.

So it is more likely then you have a setup problem with this simulation but not the other. Can you post an image of both geometries?

You will probably be able to use some small timesteps to start it off and increase them from there. Adaptive time steps (adapting to 3-5 coeff loops per...

Trust me, and believe. It is diverging. I have seen it a zillion times. And in this case you seem to be using a massive time step so the first thing I...

Been asked a million times, I really should write an FAQ on this. Floating point error means your simulation has diverged. You need to improve numerical stability. To fix it consider smaller time...
