November 28, 2010, 20:12	Problem with rotating model	#1
amoolraina New Member Amool A Raina Join Date: May 2010 Posts: 14 Rep Power: 15	I am trying to simulate a rotating wind turbine using Ansys Fluent. After creating a 120 degree periodic domain that has been cut out of a pipe, I am getting a reversed flow irrespective of the length of the domain. My model finally crashes after 2000 iterations with the turbulent viscosity increasing beyond limits. I have tried relaxing the parameters but they arent helping at all. Any ideas for possible solutions?
