Name
Direct (DirectSolver) — A non-iterative non-sparse matrix solver using LU decomposition. Uses a lot of memory. Not recommended if the finite element mesh is large.
Synopsis
DirectSolver()
Description
The Direct solver uses LU decomposition to solve a matrix
equation. This method is not an iterative
method, so there is no tolerance to specify. However, it uses a
lot of memory because it must store the whole matrix, even the
zero components. The iterative solvers are usually more
appropriate for finite element matrices, which are generally
sparse.
