Good Morning, I am a student learning to simulate magnetostrictive materials together with a piezoelectric one, simulate in a stationary state a bilayer (magn + piezo) and I obtained that the magnetostrictive material becomes saturated due to deformation but this is not reflected in the voltage of the piezoelectric material. Also I need to simulate the same bilayer, but submitting to the material two magnetic fields, one alternate and another static, but in comsol only gives me the option of placing one, if someone can guide me how to do it in COMSOL 5.2 I will be grateful, greetings.

Hi There,
You might be looking for the Small Signal Analysis in Frequency Domain. In this case, you will have a large DC field and a small purturbance (AC field) around the DC field.
Please see this example: https://www.comsol.com/model/small-signal-analysis-of-an-inductor-2128
