class Kratos::NodalResidualBasedEliminationBuilderAndSolverContinuity< TSparseSpace, TDenseSpace, TLinearSolver >
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. Calculation of the reactions involves a cost very similiar to the calculation of the total residual
