hi every one:
how can i run interfoam in steady state way? i find if i set the ddt term to steady state in fvScheme,it still run in unsteady way, but it run too waste of time. can it run in steady state way like what in ANSYS CFX. for i just want to a time avarage value of flow field.

thanks
yours wayne
