# cglen

Specify the length of the coarse grid (in a focusing calculation) for an automatic multigrid (mg-auto, mg-para) Poisson-Boltzmann calculation. This may be different in each direction.

    cglen {xlen ylen zlen}

This is the starting mesh, so it should be large enough to complete enclose the biomolecule and ensure that the chosen boundary condition (see bcfl) is appropriate.

`xlen ylen zlen`
  Grid lengths (floating point numbers) in the x-, y-, and z-directions in Å.
