iAPBS is a C/C++/Fortran interface to APBS, fast and powerful Poisson-Boltzmann equation solver. This interface enables access to most of APBS capability from within any C/C++ or Fortran code. In addition to the reference implementation, iAPBS/CHARMM, iAPBS/NAMD and iAPBS/Amber modules are also available. These modules extend CHARMM, NAMD and Amber functionality with APBS routines for electrostatic calculations.
Current version of the interface is 3.8.0 (ChangeLog). Please report any problems to Robert Konecny (firstname.lastname@example.org).
User documentation is available here. This includes installation instructions for Amber, CHARMM and NAMD modules and how to use them, with examples.
Detailed description of the iAPBS wrapper library can be found in the Programmer's Guide (html or pdf).
iAPBS is now part of the official APBS distribution. Please download APBS source code from github.
