virtual void Hermes::Solvers::DiscreteProblemInterface< Scalar >::assemble ( Scalar *  coeff_vec,

pure virtual

Assembling. General assembling procedure for nonlinear problems. coeff_vec is the previous Newton vector. If force_diagonal_block == true, then (zero) matrix antries are created in diagonal blocks even if corresponding matrix weak forms do not exist. This is useful if the matrix is later to be merged with a matrix that has nonzeros in these blocks. The Table serves for optional weighting of matrix blocks in systems. The parameter add_dir_lift decides whether Dirichlet lift will be added while coeff_vec is converted into Solutions.

Assembling. Without the matrix.

protectedpure virtual

Preassembling. Precalculate matrix sparse structure. If force_diagonal_block == true, then (zero) matrix antries are created in diagonal blocks even if corresponding matrix weak forms do not exist. This is useful if the matrix is later to be merged with a matrix that has nonzeros in these blocks. The Table serves for optional weighting of matrix blocks in systems.
