Howdy Foamers:
I would like to ask question before considering implementing a new boundary condition for it. My domain has two cyclic boundaries, where flow out in one of the cyclic boundaries will be fed back to the other cyclic boundary. However, I would like to prevent other variables (e.g., species) from feeding back. I could contemplate writing a new boundary condition where cyclic is applied to velocity only, and everything else will be set to zeroGradient, but before I do that I would like to know if there already exists a way to do this in OpenFOAM. Thanks in advance, Gerry. |
