24 Class
25  Foam::SmoothSolver
26 
27 Description
28  Iterative solver for symmetric and asymmetric matrices which uses a
29  run-time selected smoother e.g. GaussSeidel to converge the solution to
30  the required tolerance. To improve efficiency, the residual is evaluated
31  after every nSweeps smoothing iterations.
