I am doing an optoelectronics project in COMSOL software. Actually, this project is a solar cells simulation. I defined the geometry of the structure. I have also specified the physics of the problem. When I do a separate study on each of the physics, the output is displayed to me. But when I study both biooptic and semiconductor physics together, the software shows me an error message.
The error message and the COMSOL file are attached. Please guide me if you can.
