Reply To: Problem with the UDF and the default turbulent viscosity of Realizable k-e

I'm assuming PHI is in radians? Otherwise the code doesn't look to have any obvious problems. I'd favour more intenting and comments for future reference and I'd tend to avoid 2-3 character variables where possible in case anything overlaps with a Fluent value. 

I've not had a detailed look, and won't be doing any debugging. If you plot contours, lines  etc are the results off by an offset, factor or just random differences?
