Discontinuous boundary conditions #17363
-
I'm solving a system of coupled equations (heat + diffusion) for a system of concentric rings. There is a gap between the rings, which I would rather not model, that leads to a difference in temperature between the inner-right and outer-left boundaries of the rings. I can specify these as a Dirichlet boundary condition (time-dependent function). I also have a relationship that defines the concentration at either side of the interface as a function of the temperature. Do I need to use XFEM to model something like this? If so, how would I specify a function-based Dirichlet boundary condition, and how would I specify an equilibrium relationship across the boundary? |

This sounds like something that our Constraints System might handle. I have not used it, perhaps @lindsayad or @bwspenc could verify that I am understanding correctly. |
