Hello Everyone,
I am simulating natural convection in a 2-D square cavity with hot wall at bottom and all other walls at ambient temperatures. I am using buoyantBoussinessqPimpleFoam My problem is that I want to set x-velocity component to be 0 at the side walls, whereas, I want to set a Neumann condition for the y-velocity at the side walls. Kindly please help me how to achieve this. Thank You. Last edited by Pavithra; June 11, 2019 at 02:57. Reason: A small change |

Hi,
Maybe the directionMixed boundary condition could be helpful? Note that I did not use it myself, but it seems like you can specify Dirichlet and Neumann boundary conditions for each component using the valueFraction. Regards, Tom |
