Hi @udemirezen , I'm not sure I understand the notation used here. Can you clarify a little bit more?
Hi @udemirezen , I'm not sure I understand the notation used here. Can you clarify a little bit more?
Sorry for unclear explanation. I mean:
these kind of boundary conditions. Here rl is lower value, ru is upper value rl =0 and ru=1 in this case.

especially these Boundary conditions that i wanted to ask:
Is This type of BVC possible to implement? Thank you
Hi, this looks like a Robin condition if I understand correctly. Currently, we don't have a stable implementation. However, I would recommend adding the boundary constraint to your loss function. You can override the additional_loss
function of your solver. Check this documentation and this line of code for more. Note your new additional_loss(self, residual, funcs, coords)
function must return a scalar (usually mean squared residual) that will be minimized.
Feel free to reach out if are not sure how to do that.
Hi, Can we create a special type of boundary condition given below:
Dg(s(t,1)) ~ ks*(sa-s(t,1)),
Dg is the differentiation on r (spherical coordinates) Dg(f(t,r))/Dr. If yes, could you show it? Thank you
