Submitted: 20 September, 2013. Accepted: 24 October, 2013. This paper presents a study of the effect of solvent-filled cavities and Stern layers in a biomolecular electrostatics solver based on a boundary integral formulation. The tool for this study was the PyGBe code: a solver for biomolecular electrostatics using Python, GPUs and boundary elements. To determine... Continue »

It presents the PyGBe code (pronounced 'pig-bee'), which solves the linearized Poisson-Boltzmann equation using a boundary element method, BEM. The underlying dense systems are solved using a Krylov-subspace method, accelerated with... Continue »
The PyGBe code solves the linearized Poisson-Boltzmann equation using a boundary-integral formulation. We use a boundary element method with a collocation approach, and solve it via a Krylov-subspace method. To do this efficiently, the matrix-vector multiplications in the Krylov iterations are accelerated with a... Continue »
