My situation is to solve a three-layer model with a system of PDEs. The bottom and top boundary conditions are known, while the interface of the different layers is prescribed to have the same heat flux across. How can I address the problem using pdepe or PDE tools? Especially the boundary conditions.

I'm not a expert on this, but did you try to add some "intermediate" condition in the function where you define function
[c,f,s] = pdex1pde(x,t,u,DuDx)
Did you write your code without the boundary conditions?
