Auto stopping a transient simulation

PulpCairns · September 21, 2016, 13:25

Hi

I am running a transient internal flow simulation. I would like to keep simulating time steps until the total pressure of the fluid becomes constant (within a tolerance). I do not know how many timesteps will be required before starting the simulation.

Is there a way to implement this in fluent. I have tried looking into the convergence manager and setting up a total volume integral monitor but I can't figure out how to stop a simulation when this becomes constant.

Thanks for any help

This has been solved.

The problem was the stopping criteria was too small and was never met. Noobs mistake really.

How do you setup a stopping criterion to automatically stop the simulation when the stopping criterion is met?
