Steady state solution used as initial condition for Unsteady

junpepe · December 5, 2012, 11:24

Hello everyone!
I'm quite new to Star-CCM+.
I'm trying to simulate aircraft pitching (subsonic, constant density, segregated solver) using DFBI and 6-DOF models.
I need to use a steady state solution (velocity and pressure fields in the whole domain) as initial condition for my unsteady case. How can I do it?
Thanks in advance.

You can get a table including information from your inlets. Then insert this table as the initial values of the inlet in the unsteady case.
