Hi, dear all,

I am trying out the FSI module, and my model somewhat get converge.
I apply the inlet a pulse wave inlet uniform velocity, with outlet pressure=0, things goes well, but at 10.5s, the sin wave do not looks like what it should look, as 1st attachment.

I want to know what is going wrong so l use laminar flow module, all things go well as attach,a wave occur. as in second attachment
both use time dependent solver and exactly the same solver setting.

so i suspect the error comes from the solid mechanics during fluid structure interaction.

is anyone share experience with me?may i know how i can fix the small "dip" at the last second?
