Hello We are trying to simulate a Fluid Structure Interaction (FSI) between the piezofan and the surrounding air using COMSOL. We managed to simulate the piezofan using Eigenfrequency for the piezoelectric effect, but when we tried integrating it with FSI we encountered multiple issues and realized that it's too complex to solve. We then resorted to applying a sinusoidal force to the blade, that leads to the needed deflection for one cycle (which is for one second, so not at the correct frequency). The simulation converged for small forces (up till 1N), but not at the desired force to give us the required deflection (700N). The Error given is regarding 1 void equation in the matrix of the wall velocity variable. Any advice ?
