Cavity filling, interFoam

surendra22 · October 18, 2019, 03:08

hello everyone,
I am new to OpenFoam and I am working on mould/cavity filling simulation.
I am using InterFoam solver and I want to fill the cavity completely with fluid(molten metal) letting air to escape through the outlet but after doing some homework I think it is not possible with InletOutlet boundary condition.

Please, Can anyone suggest me how to model this problem, which boundary condition should be used?

I have attached some png files for defining my geometry.

Thanks

I am attaching my case file.
I would appreciate any comments or suggestions.

Actually, I need to model my mesh boundaries as porous media using Darcy's equation.
Got some help from a thread
Permeability filling of container outlet condition

Am I on the right way?

Thanks
