How to solve foer error code?

Using SimScale
1

Hi
This is s.o.ahn in korea.
I use first time simscale so it is not easy solve error code.
Can you sover below error code.
“The simulation contains only outlet boundary conditions for the fluid region PSU_BACK_POROUS, which will most likely lead to global continuity errors. Please select an additional inlet boundary condition.”
Above error that it is add “inlet” but how to do?
Best your regards.

Hi @soahn1, thanks for posting

Since we don’t have access to your project, we can’t know for sure what the issue is. However, for fluid flow simulations you need a driving force for the velocity, and everything coming in needs to come out. That’s why the most usual combination of boundary conditions is Velocity inlet + Pressure outlet.

You can take the cases in our tutorials page as examples:
