Any help with floating point exception on a cyclone hex mesh?

I have built a hexahedral mesh for the cyclone separator via many divisions for meshing, and after refining it now reaches a floating point exception quite quickly.

Using RSM and double precision.

Any thoughts on why? We have greatly reduced skewness in the refinements and the mesh is now much higher quality than the previous mesh that successfully ran for many time steps.

thanks
