Hello, I am quite curious about the function of submodeling and directly tried to model a problem to understand this feature completely and use it for further researches.

I am modeling photovoltaic-structures wich are laminated in a bonded contact. After solving the global model, I'd like to make a submodel study and use a finer net and also make some little geometric changes on the silicon-solar-cells (for example electrical contacts between cells and also on top/botton of the cells). To make the geometric changes, I just created a dublicate of the submodel-study so the global model doesn't get updated after changing the submodel. When i start the simulation, it tells me that I have to use the function INCOMPATIBLE NET at the global model in order to solve the submodel with bonded contacts.

I press yes and it starts.

The problem is: It doesn't seem to find a solution after activating the incompatible net feature for bonded contacts. It just did try to solve it iterating at 33.3% without any solution for three days at a simulation wich usually took about 4 hours to solve.

Anything I can do about this?

With special greetings!

Wolfgang
