Main Question or Discussion Point
Hi. Can anyone help me to figure out how to run multiple studies in COMSOL? I want to first compute the displacement of a membrane using temperature load and then find the capacitance between two electrodes using electrostatics. The idea is that as the membrane moves upwards the capacitance will decrease (the top electrode of capacitor is on top of the membrane). Given that i need to find B using the results of A I think I should use 2 studies but even when i select only thermal stress and electromechanics for study 1 it still doesn't provide the right solution if electrostatics study is added to the model. But if i use thermal stress and electromechanics without electrostatics in the model it gives perfect results. That makes me conclude that even after removing electrostatics from the study it still uses some variables from it which mess up the calculations. I've tried everything i could think of so any help would be appreciated.
