Channel Flow rhoSimpleFoam error
 
Hello,

I am new to OpenFOAM and I am trying to model a steady, compressible, turbulent flow through a channel using a rhoSimpleFoam solver but I am getting a floating point exception error which I can not find the source of. Any help that anyone can offer is greatly appreciated.
