| Class | |
| Foam::smoothSolver | |
| Description | |
| Iterative solver for symmetric and asymmetric matrices which uses a | |
| run-time selected smoother e.g. GaussSeidel to converge the solution to | |
| the required tolerance. | |
| To improve efficiency, the residual is evaluated after every nSweeps | |
| smoothing iterations. | |
