interFoam running blowing up
 
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,

and when I tried to visualize it I got this:

Typical MULES blow-up, try decreasing the time-step and/or increasing the number of nAlphaSubCycles.
