Hi everyone, i want to write a UDF for unsteady condition to do some works, but i have a problem within that. i want to do one of the following items(each of them that is possible):

a) reiterating a time step with the current values of varibles (pressur/temp. ...).

b) continuing the iteration in a time step even after the convergence conditions are met (up to a iteration that i want).

please help me. i'm badly under the pressure.

Best wishes

Hi

For a), try using the patch option under Initialize.

For b), tick-off the "check convergence" option in residuals for all variables.

Regards
