ansys fsi problem I

O.K .so recently stuck in mesh in ansys fluid structure interaction.the mesh in transient structure does not work well.
It looks like there is still a long way to go.
keep on pops up
error updating cell solution in the transient structural system.
i guess most probably will need some luck
This error mostly returned while you have intersecting bodies in your problem geometry. just one of those bodies should be meshed and the other ones should be used as "Body of influence" at least in one "Sizing" feather.

I hope this could solve your problem.
Good Luck

another one
The target body that you want to scope to needs to be selected as patch conforming tetrahedron - if you don't do this it will not modify the meshing (To make target body patch conforming right click on mesh, select insert -> method -> select target body --> then select method tetrahedron)
