CFD Online Discussion Forums - smoothSolver error when solving for P in sonicFoam

Hello,

I am decently new to OpenFOAM and am attempting to run a simulation of a symmetric diamond airfoil in Mach 3 STP air.

When running sonicFoam I get this output:

Floating point exception

I am unsure of why I am getting this as I was able to solve with a different mesh and the exact same p, U, T, and controlDict files. I changed the height of my mesh in order to have the shock wave "exit" the test section.

This is my blockMeshDict file:

Any help would be greatly appreciated as it is only failing on the second Pimple iteration, no matter the time step or the number of pimple iterations per time step.
