To set the linear solver, use
The possible choices for '$SOLVER'
are:
Richardson:
A fixpoint solver using the Richardson iterationSteepestDescent:
The steepest descent solverConjugatedGradients:
A conjugated gradients solverBiCGStab:
A stabilized bi-conjugated gradients solverMinRes:
A solver based on the minimized residual algorithmRestartedGMRes:
A restarted GMRES solverChosing the preconditioner works in an analogous way:
Where the choices possible for '$PRECONDITIONER'
are:
Jacobi:
A Jacobi preconditionerGaussSeidel:
A Gauss-Seidel preconditionerSSOR:
A symmetric successive overrelaxation (SSOR) preconditionerSOR:
A successive overrelaxation (SOR) preconditionerILUn:
An ILU(n) preconditionerILU0:
A specialized (and optimized) ILU(0) preconditioner
