Combining 1D and 2D physics in a simulation

Hello,

I want to do consecutive 2D and 1D simulations of different Physics on a model. For example, I want to solve the electrostatic equations inside a 2D structure then I want to solve Schrodinger's equation at cut line inside the structure. I do not need this to be self-consistent for the time being but if there is a self-consistent way that would be great.

Best Regards,
Mohammed
