FLUENT closes during Simulation
 

Hi there,

I am running a 3D Diesel jet spray simulation using the VOF method.

The simulation seems to run ok. I set the time step size to 1e-9 sec and i am able to get results upto 3 milisecs however after this point FLUENT automatically closes down and the simulation data is lost.

Has anyone experienced this before and know of anything that may be causing this.

Thanks
Jan.
