Discretization of partial differential equations (PDE) in topological structure

[LS-Maxwell]

Woo...,OpenPNM is a very nice code and I can easily use it for my pore media simulation with pore and throat mode simulation.

I want to compute the flow problem with PDE equations in the topology structure by pore and throat model , Vornonoi structure for example. But, I can not find some detail description about how to discrete the equations in topology structure by finite difference method(FDM) or finite volume method(FVM). But I have to solve partial differential equations in this complex structure.
So , could you give me some suggestions or about it?

If I understood correctly, you should look into the algorithms module. Here, you can find some examples, which explain how to run different algorithms.
