Table 7.2 and
Table 7.3 show the solvers and preconditioners supported by
esys.finley through the PASO library. Currently direct solvers are not supported under MPI.
By default, esys.finley is using the iterative solvers SolverOptions.PCG for symmetric and SolverOptions.BICGSTAB for non-symmetric problems.
If the direct solver is selected which can be useful when solving very ill-posedequations
esys.finley uses the MKL solver package. If MKL is not available UMFPACK is used. If UMFPACK is not available
a suitable iterative solver from the PASO is used.
