Interior wall
 

Hi,
I have simulated a left ventricle flow and have put and interior geometry to act as a valve. The problem arises when this interior geometry is defined as a wall boundary condition but the flow still goes through it.
It seems like this interior geometry is ignored.
Can someone help me solve this problem?
Thanks beforehand

"interior" means the geometry is set to be transparent to flow. Go to boundary conditions and change from interior to wall, and all should work.
