Dear All,
first of all i hope this is posted in the right spot, i am new to all of this, so please fogive me 'stupid' questions. My question is, if there is a way to put two different boundary conditons in one patch. I'm using interFoam (1.5) to simulate a multi-phase channel flow, but the outflow in the end of the channel is not completely open, but has a triangular shape. I can't quite explain, so I made a drawing. The issue is that I have to set gamma, pd and U in different BCs, whereas for the outlet: U: pressureInletOutletVelocity pd: totalPressure gamma: inletOutlet and for wall: U: fixedValue pd: zeroGradient gamma: zeroGradient Is there any way to do it like nonuniform BC like here http://www.cfd-online.com/Forums/ope...condition.html since i can't make patches out of 3 vertices? I'm happy for any help! Thanks a lot in advance Conny |

Hi Conny,
to my knowledge (which can be wrong!!) it is not possible to set something like a split boundary condition. But what you could do: Make four blocks with a triangular shape instead of two rectangular blocks. Usually you should be able to define that by putting two side-lines of the building block onto each other. For example if usually you have block (0 1 2 3 4 5 6 7) for the rectangular one, you could use block (0 1 6 7 4 5 6 7) for the first block and block (0 1 2 3 0 1 6 7) for the second block. I do not know if that is a nice solution. But some time ago it worked at least for building the basis structure of something... |
