Hi everyone,
I'm trying to analyze a wind tunnel by using ANSYS 16. A few days ago, I added a cavity on the tunnel and tried to analyze the system again and I faced some problems. My solution is pressure-based, with Transition SST method. My problems are: 1. "turbulent viscosity limited to viscosity ratio of xxx in xxx cells" 2. "temperature limited to xxx in xxx cells" 3. I tried to use different methods like Standart k-omega method but the solution diverged. I also tried to edit my grid and it currently looks like the picture below. I made some research and saw that my problem migth occur because of poor meshing. I adopted my grid on Fluent but that didn't solve my issue. Some said that it can happen because of boundry conditions. I used the same boundary conditions before I added the cavity. |
