Element equation formulation

Please login with a confirmed email address before reporting spam

Dear all,
It would be really helpfull if someone could help me to get answers to some of my basic doubts.

Which method is used to formulate the element equation when we are simulating a complex problem as well as simple problems?
Is there any simple way to understand clearly what actually happens Inside the software,[Which governing equations are used,how Boundary conditions are taken mathematically,which numerial methods are used to solve the assembled matrix]when we solve a particular problem [3D problem] in COMSOL.
