Dear lvar and my friends,
Thanks for lvar for bring me back to using COMSOL, as it looks has a lot of secret recipe now :p
1. Refer to the rectangular 4.2, the wall is add in to formulate no slip condition, and i am able to formulate the same layer as fluid-solid boundary layer. The stationary solver ok, as you can see, result looks good, however, when i enable time dependent solver, it cause problem.Any idea?
2. Second model is little bit complicated. as i try to use laminar flow as initial condition, then i process to FSI module. Then it appears "wrong number of dof in linearization point" ,good to know it.
Anyway, we stick to 1st one.
Any idea?
