akeyPRE — APBS-PDB2PQR 1.6 documentation

# akeyPRE

Specifies how the initial finite element mesh should be constructed (from refinement of a very coarse 8-tetrahedron mesh prior to the solve-estimate-refine iteration in fe-manual finite element calculations. The syntax is:

    akeyPRE {key}

where `key` is a text string that specifies the method used to guide initial refinement and takes one of the values:

`unif`
  Uniform refinement
`geom`
  Geometry-based refinement at molecular surfaces and charges
