Hi there!
How do I ensure that a part of the UDF executes only once (at the beginning of) a time step and not at every time? The UDF I've written is for unsteady pressure. Since it includes saving current time data to a UDM, how do I ensure this doesn't happen every iteration within the time step? I'm using the UDM so that I can get (P_current-P_old). |

Got it! have to use 'first_iteration' or EXECUTE_AT_END.
