Hi

I am modeling vacuum assisted resin transfer molding (VARTM), and I want to capture the resin flow front in the fiber reinforcement. For that, I have added porous media to interFoam.

I have a block with two parallel porous zones with different permeability, inlet at one patch and outlet at the opposite patch.

My problem is that there are no flow though the thickness, because there is no pressure difference between the two phases where the block is partly filled. Please see the attachments.

Is it possible to define a constant pressure for my air phase with interFoam, which provides a pressure drag normal to the phase interface?

Thanks
Simon

Hi Simon,
did you manage to simulate VARTM until now?
I'm also trying to simulate the RTM process and maybe we could reactivate this thread.

Greetings, Alex
