00024 Class
00025     Foam::smoothSolver
00026 
00027 Description
00028     Iterative solver for symmetric and assymetric matrices which uses a
00029     run-time selected smoother e.g. GaussSeidel to converge the solution to
00030     the required tolerance.
00031 
00032     To improve efficiency, the residual is evaluated after every nSweeps
00033     smoothing iterations.
