Reply To: FLUENT MultiPhase – floating point exception 6hrs into calculations

OK, I think you need to do some reading on precessing vortex cores. Replot the two velocity contours with node values off and zoom in around where the core is forming. 

Turbulence isn't constant, it's just below 0.026 m2/s2 in most of the domain. If you look on the contour panel you'll see "Auto Range": it's not always helpful.
