Hi,
I am a new user of Openfoam and I tried to realize a chtMultiRegionSimpleFoam case. It is a solid encircled by air with 4 regions: -Solid - Air1, Air2 and Air3 Between Air1/Air2 and Air2/Air3 I don't know what is the boundary condition for the velocity to illustrate the internal condition (Air1_to_Air2 and Air2_to_Air3). Someone can help me ? Thank you very much, Lucie |

Hi,
as far as I know it is problematic to work with fluid-to-fluid interfaces with chtMultiRegionFoam. One solution could be to create only one fluid region. If you can joint all the Air regions, you won't have that problem. |
