Hello

 

I want to simulate a flood case for an hour, I mean, when the simulation ends, the final result should represent the flood status after one 1 hour of flood. For this, I set the number of time steps to 3600 and the time step size is 1. However, the simulation didn't converge, so I reduced the time step size to 0.01, and, accordingly, I changed the number of time steps to 360000. Is this correct?

Hello,

If the simulation does not converge, please reduce the time step size more. But let me inform you. Non-convergence of the solution depends on other factors like mesh and case setup also.

Yes, solution duration (model time) is time step size x number of time steps. As Essence comments you also need to converge each time step.

ok, thanks!
