APBS stands for Adaptive Poisson-Boltzmann Solver. It is a software package used primarily in computational biology and chemistry for solving the Poisson-Boltzmann equation, which is a mathematical representation of electrostatic interactions in systems like proteins, nucleic acids, and membranes in a solvent. APBS is particularly useful for calculating electrostatic potentials, which can help researchers understand how molecular structures interact with each other and their environment, especially in biological contexts.
