Hi, foamers
I just run a very simple case. In my case, I just put air in the chamber and let the piston move up and down. The initial input is just like the -180 folder in the enginefoam tutorial. The value of temperature and pressure are very reasonable. However, the epsilon value is too high (initial value is 400, but the maximum value is 150000). The turbulence model is k-epsilon model. Could any one give me some suggestion what is wrong with this? Thanks very much. |
