Closing the Pressure Outlet during the run
 

Hi everyone

What i want is to close one of the few Pressure Outlet boundaries - without changing manually type to Wall.
I tried setting Boundary->Physics Conditions->Pressure Jump Options->Porous resistances to be a smooth (in time) function of high value (~1.0E+4 - both Viscous and Inertial components), but it leads to energy convergence.

Any ideas on closing in other ways (a simple way - not any kind of Overset Mesh etc) or fixing my method?

// Average velocity in my case is 1 to 5 m/s, Ideal Gas model is used (Temperature - [0..1800] C).
