Hello Dear Foamers,
I wanted to simulate a flow over a felexible pipe,but before that i wanted to make a simple test case ,but I have a problem with. My simple test case is a fluid which moves around a beam which its both ends are fixed. When I run the case some thing goes worng with the mesh. When the fluid pass the beam it start to bend after a while some cells start to apper. after a while when beam goes back they strat to disppear.

p.s. I examined :velocitylaplacian ,laplace and psudo solid, they all had problem.
p.s.s there is an animation of this here to see the problem better: https://www.mediafire.com/?uugb58do8wb6n85

thank you all.
