Carno Member carno Join Date: Mar 2009 Posts: 70 Rep Power: 17	HI All, I have been trying to solve a CHT problem, with air, water and solid. It is a test case before solving the main problem. It is a simple box with two tubes. Box is of steel and two tubes contain water and gas respectively. I have solved the case with Laminar case and results are reasonable. But as soon as I twitched on turbulence model with "turbulence true;" in the turbulence properties dict, the run crashes. I have tried numerous combinations. The run goes well when "turbulence false;" Please help !
