Thaks for your response, actually I've removed the inflation. Due to inflation are organized cells they were having problems when the are "compressed" by the cell movement. 

Now, I've done a sphere of influence sizing and decreased the pressure coeficient the simulation finished with no prolems.

The only thing now is the time motion history(I need it to se if my experimental simulation is verified), I've selected to send it to my paste but I don't knows its extension.(Im my paste there are a .LOCK and a .Project_Cache) Do you know if there is any of these?
