Hi,
I'm trying to model blood flow and cholesterol concentration in an artery. because of high aspect ratio between the free blood flow region(lumen) and the arterial wall layers, and high velocity and concentration gradients in the porous wall, It would be more efficient to use incompatible mesh and prevent memory allocation errors.
I've tried to mesh the free and porous parts individually, but seems COMSOL doesn't implement flow continuity and uses wall boundary condition instead even when using pair flow continuity.
actually I don't know which branch of the pair flow continuity to use and how to do that.
simplified geometry is attached.
Thanks.
