setPreSMOResidual()

void NonlinearSystemBase::setPreSMOResidual ( bool  use )

inlineinherited

Set whether to evaluate the pre-SMO residual and use it in the subsequent relative convergence checks.

If set to true, an additional residual evaluation is performed before any solution-modifying object is executed, and before the initial (0-th nonlinear iteration) residual evaluation. Such residual is referred to as the pre-SMO residual. If the pre-SMO residual is evaluated, it is used in the subsequent relative convergence checks.

If set to false, no residual evaluation takes place before the initial residual evaluation, and the initial residual is used in the subsequent relative convergence checks. This mode is recommended for performance-critical code as it avoids the additional pre-SMO residual evaluation.

setupColoringFiniteDifferencedPreconditioner()

void NonlinearSystem::setupColoringFiniteDifferencedPreconditioner ( )

private

According to the nonzero pattern provided in the matrix, a graph is constructed.

A coloring algorithm is applied to the graph. The graph is partitioned into several independent subgraphs (colors), and a finte difference method is applied color-by-color to form a preconditioning matrix. If the number of colors is small, this method is much faster than the standard FD. But there is an issue. If the matrix provided by users does not represent the actual structure of the true Jacobian, the matrix computed via coloring could be wrong or inaccurate. In this case, users should switch to the standard finite difference method.
