Ouch! The dreaded floating point error!

Your solution may have blown up, and you may be getting huge (unrealistic) pressures/velocities/densities etc...

What are you modelling? Maybe one of your BC's is wrong? Also, some solution methods are highly unstable, maybe try with more default methods (pressure based segregated with 1st order disc.).

Also, are the residuals converging on a solution? If not, try halving your under relaxation factors.
