Floating point error
 
I have a problem in converge the solution. It run for about 170 time steps and then indicate "Floating point error, invalid number". I have tried with different input and it still happen. Can any of you have any ideas where should be gone wrong?

Thank you so much

What's the problem you are simulating ? which code ? have you got the source code ? Have you examined all the fields after the error ?

One possibility is your solution has become unstable. You could try smaller time steps.
