Dear Foamers,
I am doing a liquid jet simulation using interFoam, my geometry is OK according to checkMesh. After setting the suitable boundary conditions I ran my case and after moving about the third way of my simulation, the running had some errors and stopped, I do not why? .. can any body helps me please because I am not that good in analyzing these kinds of errors. Following is what I got in my log file and later what I got when I tried to visualize the results I got so far.....
Sandy,

santiagomarquezd will become famous soon enough
Typical MULES blow-up, try decreasing the time-step and/or increasing the number of nAlphaSubCycles.

Regards.

Dear Foamers,

I am simulating a case which involves 2 phases with very high pressure difference from inlet to outlet using interFOAM.
I have set up the case and trying to run the case but its blowing up.
Mech check was ok. setFields was perfect.

I have attached the case set up and also log file.

Please guide me where its going wrong.

Regards,
Sam
