Ramana,

Please elaborate. In my experience, you can't expect other participants in this Discussion Forum will invest their time into trying to assist with so little information to go on. The most we can tell based on what you posted is thatapparently something happens at t~0.004 seconds (Perhaps one of your model inputs suddenly varies?) such that the solver runs out of memory. You probably already realized that though. Again, more information would help. Please consider posting your .mph file.

Best,

Jeff
