There is a pre-defined analysis type for this in COMSOL called “Prestressed Analysis – Frequency Domain”. Regarding switching materials between the two studies/steps it is possible and in some cases it is the most suitable way. However, you lose the benefits of the pre-stress analysis since the new material is no longer in equilibrium at the start of the frequency response step.
