 April 15, 2013, 06:04 interFoam running blowing up #1 Member   sandy Join Date: Mar 2013 Location: Cardiff, UK Posts: 71 Rep Power: 4 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.....

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
