I have designed the piezoelectric energy harvester structure in COMSOL. I have doubt regarding finding power. I found that current will be obtained by integrating the current density. Here is my doubt, generally to get power is to multiply voltage and current, but in COMSOL we will get open circuit voltage and current. In this situation it is right way to multiply open circuit voltage and current to get power without load. Another doubt is that I tried to connect the resistor to my piezo model through SPICE netlist but it is not working. Please clarify my doubts and grateful to help me.
