• If you only know u1 and u2 on some locations, use PointSetBC https://deepxde.readthedocs.io/en/latest/modules/deepxde.html#deepxde.boundary_conditions.PointSetBC and Very complicated boundary #264
• They are Dirichlent and Neumann BCs.

@lululxvi Thank you for your reply, it's useful for me. In fact, u1 and u2 are not PointSetBc. In mathematic, they are given abstract functions with no concrete expressions(and do not know any locations). I will continue to study how to deal with this problem. If there are any results, I will share them here for the first time.
