Dear Foamers,


I am wondering if anyone has tried something like this. I have a rectangular domain with 3 solid walls. On the fourth wall, I want to split it between a time-varying mapped Dirichlet condition and a zero gradient condition. However, I want the point where the wall is split into two patches to move up and down with time. See the attached hand-drawn diagram. I am solving with buoyantBoussinesqPimpleFoam, and the two patches have different T values.



One way to solve this might be to use a single patch with #codestream, but I was wondering if anyone had a more elegant solution? I can code the zerogradient condition into a #codestream from the ground up, but am probably not good enough to manage the mapped condition.


Thanks!
