# mg-manual

Manually-configured finite differnece multigrid Poisson-Boltzmann calculations.

This is a standard single-point multigrid PBE calculation without focusing or additional refinement. The `mg-manual` calculation offers the most control of parameters to the user. Several of these calculations can be strung together to perform focusing calculations by judicious choice of the bcfl flag; however, the setup of the focusing is not automated as it is in mg-auto and mg-para calculations and therefore this command should primarily be used by more experienced users.
