Modeling Insulin Flow Through Porous Adipose Tissue

Hello Fellow Comsol Users,

I am getting stuck attempting to model insulin flow. As of now, I am using laminar flow to model insulin being injected from a canulla into adipose. At this point, I used Darcy's law to simulate the flow from the cannula through the adipose tissue (porous) into the blood vessel.

I used a simple 2D geometry, and am having trouble coupling the two physics. Any help would be appreciated.

I can upload the file for the model.
