SolverΒΆ
| Type: | enum |
|---|---|
| Range: | BiCGSTAB, GMRES, QMR |
| Default: | GMRES |
| Appearance: | simple |
Selection of the classical iterative solver scheme:
- GMRES robust solver, but relatively high memory usage especially for many right hand side problems
- QMR smaller memory footprint, but requires two matrix (preconditioner) calls per iteration, which increases computation time per iteration especially for expensive proconditioners
- BiCGSTAB similar as
QMRbut more failure prone thanQMR
