FSI foam-extend using meshes from ANSA

Dear all,

Was wondering if anyone has encountered this problem I've been stuck on for a while now.

I successfully ran the 3dTube example in foam-extend extend-bazaar, but I have then tried using the fsiFoam solver for an idealised bifurcation

Unfortunately I get floating point exception errors. I have generated the meshes for the fluid and solid domain in ANSA (attachment). Having thought my mesh was the cause I've tried to replicate the mesh in the 3dTube example in ANSA, but this case crashes after a few timesteps with floating point exception errors also.

Am I being naive to the requirements of the case set-up for the solver? Any help greatly appreciated

Best wishes,
George
