Detailed Description

template<class TSparseSpace, class TDenseSpace, class TLinearSolver>
class Kratos::SolutionBuilderAndSolver< TSparseSpace, TDenseSpace, TLinearSolver >

Solution Buider and Solver base class.

Short class definition. Current class provides an implementation for standard builder and solving operations.

the RHS is constituted by the unbalanced loads (residual)

Degrees of freedom are reordered putting the restrained degrees of freedom at the end of the system ordered in reverse order with respect to the DofSet.

Imposition of the dirichlet conditions is naturally dealt with as the residual already contains this information.

This is the base class for the building and solving the solution system
