Open Source Java Simulation Software

GridLAB-D is a new power system simulation tool that provides valuable information to users who design and operate electric power transmission and distribution systems, and to utilities that wish to take advantage of the latest smart grid technology. It incorporates advanced modeling techniques with high-performance algorithms to deliver the latest in end-use load modeling technology integrated with three-phase unbalanced power flow, and retail market systems. Historically, the inability to effectively model and evaluate smart grid technologies has been a barrier to adoption; GridLAB-D is designed to address this problem.

PUPIL (Program for User Package Interface and Linking), is a software environment that allows developers to link quickly and efficiently together multiple pieces of software in a fully automated multi-scale simulation. More specifically, it supports QM/MM MD simulations where the user might choose among any of the different MD engines and QM engines, which are connected to PUPIL as external programs through a tiny specific interface. One of the main advantages here is that the user can use most of the functionalities that may have those external programs interfaced without the necessity to be reimplemented again on independent interfaces. In fact, this simulation interface concentrates all the common code involved in the coupling terms of the QM/MM approach.

The Gecko Hamaker open-source software project is a full implementation of the fully retarded Lifshitz formulations for isotropic and anisotropic plane-plane and cylinder-cylinder interactions with intervening interlayer materials, planar systems of up to 99 layers, and graded interfaces for the modeling of grain boundaries or other continuously changing systems, accompanied by a database of material optical properties spectra. The machine-readable optical property database is available for download and as a web service and makes available the full spectral optical properties of over 150 materials from both ab initio calculations and experimental measurements.
