rhopimplefoam,transient or steady state?

immortality · November 23, 2012, 05:46

as its obvious my question is that rhopimplefoam can be used for transient problems or only for steady state.if latter can I add required terms including time for using in transients?
Thanks

rhoPimpleFoam is for transient simulations
rhoSimpleFoam is for steady-state simulations

If you go to the solver file itself, you will get the description.

In addition, someone correct me if I'm wrong, but you could use a transient solver, with coEuler time scheme and run until steady-state is achieved.

thank you very much.it is pressure based.am I right?how can understand that a solver is pressure based or density based?
Thank you again.
