superSonic Flow around sphere
 

I am trying to solve the supersonic flow around a sphere. I have a small sphere inside a large sphere as my geometry. I have the grid generated with snappy.

Could someone tell me how I set the fields (U,p,T) for the outer sphere? I am planning to use the sonicFoam solver. I am just getting a floating point exception each time I run. I have just copied the fvSchemes and fvSolution file from the tutorial "forwardStep". Any suggestions will be deeply appreciated.

Thank you.
