Hi foamers,
Recently I was applying inletOutlet boundary conditions for stopping the reverse flow when simulating a 2D- rotor section. However, the case was collapse after running some steps. The reason is that, the inletOutlet boundary condition doesn't really stop the reverse flow. The a strong reverse flow forms a shock wave, messing every thing up. Please see the following picture (Screenshot_2017-04-29_20-36-18.jpg). The boundary condition setup is: Code:
patch_outlet { type inletOutlet; inletValue uniform(0 0 0); } I'll appreciate every comment. Thanks, Janry |

Hi. I'm a begginer but most of my inletoutlet patch contains "value" parameter.
