Initial value:

=
      "Set to 'True' to use a separate bottom solver on the coarsest level "
      "instead of pre-smoothing. The bottom solver typically builds the matrix "
      "explicitly and inverts it directly. Use the bottom solver if "
      "pre-smoothing is not sufficiently effective on the bottom grid. "
      "The bottom solver can significantly cut down the number of iterations "
      "needed to converge to the solution at the cost of building the matrix "
      "explicitly and inverting it directly on the coarsest level."
