Re: COMSOL help needed. (RF module - Heating of water using waveguide)

Ok, so that is what would happen if you would hack your microwave oven to work with the door open. But that is no explanation of why your water heats so fast, I would instead expect a lot of energy to escape through port 2, so that less of it ends up in your water. Frankly I have no idea of why your results are not correct. Have you tried if mesh refinement/coarsening has any influence on the result?
