Hello guys, I have developed the system of coupled partial differential equations for piezoelectic specimen. I have 4 dependent variables (, , and ). First 3 being displacements and stands for electric potential. As they will be having different units and COMSOL PDE interface requires all the dependent variables to have same units. Do I need to non-dimensionalize the system of PDEs or can I just set the Unit system as 'None'? Any help is much appreciated. Thank you.
