# usemesh

Specify the external finite element mesh to be used in the finite element Poisson-Boltzmann calculation (fe-manual). These must have been input via an earlier READ mesh statement (see READ input file section). The syntax is:

    usemesh {id}

where `id` is an integer ID specifying the particular map read in with READ input file section. These IDs are assigned sequentially, starting from 1, and incremented independently for each mesh read by APBS.
