Re: Fluid structure interaction module discussion 2

Hi, Siyuan,

Thank you for supporting this discussion.
I agree with what lvar and you say, FSI boundary layer should not have anything.
I would encourage you using FSI module rather than separate module to make your result easily interpreted, as i found out actually they are nice to use, as all in one.If you notice, in FSI module, there is one FSI boundary interface, while blood vessel one do not have.

I made a balloon fill in with fluid,start from simple stretch. It is not function, i will try in weekend see can fix the problem or not. I think the problem come from the fix constraint, as if we want something to be expand, we should not fix any line, but if we do not fix any line, the reaction force cannot be measured.It make me feel weird. you may run the model and you can see the rupture of balloon.

The moving wall also is a problem for me, as i am wondering how i can let the external wall moving.

I will update you all what is the conclusion if i fix the problem.

lvar ,you and others are free to join this forum, so we can reduce question which send to comsol support.
