The question is, can you put your problem into the class of equations you can solve using solvepde? Make a problem that depends only on x, say, not on y, formulate it in two dimensions, make sure you use the correct kind of boundary conditions, and then it is a two-dimensional formulation but the solution depends on x alone. If your problem can be put in the framework, then solvepde can solve it.
