Non-dimensionalization of PDE

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.
