Hi Foamers
I want to solve a compressible case on a backStep Flow, but It is not converging. I want to make the boundary conditions with defined velocity on inlet and defined pressure on outlet. I also want to make a large thermal gradient on down wall. Large temperature difference about 3000 c will make a great heat transfer and cause the flow to expand . The velocity is low, but due to great temperature gradient and expansion, I would like to solve it as a compressible case with RhoPisoFoam. The problem is that it stops, giving out error for a small number of timesteps. I`m not sure about the boundary conditions and the control definitions. If any body can help me I would be glad. If you need to see my case , please send me email asking for it. sheday3@uic.edu More Feel Stabilized. |
