OOF2: The Manual

Name

Direct (DirectMatrixSolver) — A non-iterative non-sparse matrix solver using LU decomposition. Uses a lot of memory. Not recommended if the finite element mesh is large.

Description

DirectMatrixSolver is a matrix equation solver used in AdvancedSolverMode. It uses the LAPACK dgesv function to solve equations via LU decomposition. This requires the matrix to to converted from the sparse format used in OOF2 to a full represention, which uses a lot of memory. It may be faster and more accurate for small matrices, however.
