Detailed Description

structure for User Loop Methods on finite elements

It can be used to calculate stiffness matrices, residuals, load vectors etc. It is low level class however in some class users looking for speed and efficiency, can use it directly.

This class is used with Interface::loop_finite_elements, where user overloaded operator FEMethod::operator() is executed for each element in the problem. Class have to additional methods which are overloaded by user, FEMethod::preProcess() and FEMethod::postProcess() executed at beginning and end of the loop over problem elements, respectively.

Examples: UnsaturatedFlow.hpp, and simple_elasticity.cpp.
