2D Darcy's Law Model

Please login with a confirmed email address before reporting spam

I am currently doing a research and for this research I want to model the intrusion of air into concrete. Mainly researching the intrusion depth as results of the applied pressure difference. For this I have decided to make use of COMSOL model based on Darcy's Law. However, due to my lack of experience with COMSOL I am not getting results that seem acceptable.

The situation I created in COMSOL (atleast, I think I have created) is simplified to the png added.

To give sufficient information, I have also added my model. I personally think the problem is in the physics. If anyone could help or give tips that would be appreciated.
