openfoam pressure driven flow
 
Hi foamers,

I am running steady-state laminar flow with openFOAM using simpleFOAM solver.

I applied both inlet and outlet as pressure BC.

During the computation, the flow velocity in the domain starts out too high with this BC set-up.

How I can control/limit this flow velocity to help better convergence? Do I need to adjust relaxation factor or use better initial condition?

If you need more information, let me know so I can provide.

Thanks,

Pete
