Re: Fluid structure interaction module discussion 2

Dear lvar,

Thank you for knowledge sharing, what you say i will made in my next model and open the new discussion.;p
by the way, the model get converge, it can converge smoothly, in my computer just few minutes..thanks lvar.

now try some real application,
I intends to simulate the large deformation, so i formulate the inlet as laminar inflow with pressure with 20mmHg, while not outlet, quote from support:
"if you do not have outlet, your wall must move, to let model converge"

i apply boundary load on the wall, -fsi.T.stressr.where the stress come from laminar flow.as blood vessel case.
so we can expect the wall actually will expand in the middle, since i apply point fix constraint on top and bottom.

Surprisingly, the model get converge.but do not expand too much. You can play the animation.

Q
1. Why it do not deform much even with fluid load?
2. If you play the animation, while the fluid actually do not move with the wall, they are like separate each other, anyway i can improve?

Thank you
