Simulation of gravure printed devices using a resistor network

Gpvdm can be used to simulate very large area devices, by approximating the device using a 3D resistor and diode network. Arbitrary 3D structures can be generated such as hexagonal contacts and then turned into complex resistor networks which can be used to understand the flow of current through the device. Shading can be taken into account using optical models, and thus current voltage curves generated for devices >1cm2 with arbitrary geometries.
