Hi,

I want to solve PDE with Multiple Boundary Conditions.

But in terms of the problem I am interested in, there are two PDE in a different region.

For example, one set in the interval [0,1], and the other set in the interval [1,5]. The connection between the two regions is that the solutions must be continuous at x=1. The solution must also satisfy the boundary conditions like below

I am wondering whether the problem also can be solved in PDE with a time derivative.

Thanks,

Dong Woo

If you want to solve a stationary problem, take a look here:

And here is an answer for time-dependent problems:

If this does not answer your question, please supply your equations, the computational domain, the interface and boundary conditions and initial conditions.
