A spectral element method for 2D wave propagation and fracture dynamics, with emphasis on computational seismology and earthquake source dynamics.

A solver based on the spectral element method, used in conjunction with FEMAP, as a pre- and post- processor. It solves the elastic wave propagation problem, and the coupling with a piezoelectric materials for excitation and sensing. It is currently in 2D and has both static and transient capabilities.

SMMP (Simple Molecular Mechanics for Proteins) is a program library for protein simulations with an emphasis on advanced Monte Carlo algorithms. It includes various force fields to calculate the energy of a protein and protein-protein interactions.

Sandia National Laboratories’ (SNL) environmental assessment modeling tool helps optimize the design of MHK-turbine array layouts within ocean, tidal, and river systems to balance energy generation efficiency with environmental considerations. The new tool, SNL-EFDC, is an augmented version of US EPA’s Environmental Fluid Dynamics Code (EFDC) and includes; (1) a new module that simulates energy conversion (momentum withdrawal) by MHK turbine-like devices including commensurate changes in the turbulent kinetic energy and turbulent kinetic energy dissipation rate, (2) new, advanced sediment dynamics routines, and (3) augmented water quality modules. SNL-EFDC has been verified and validated against flume measurements of flow around sub-scale turbines and actuator disks.

Sempy is a Python package for the solution of partial differential equations using the spectral element method.

Computational Fluid Dynamics (CFD) solver aimed to solve multi-physics problems on unstructured grids (inviscid Euler, Navier-Stokes flows, Heat transfer). F90 based. MPI, cgns, Metis libraries used.

Tahoe is a research-oriented platform for the development of numerical methods and models for the simulation of complex material behavior.

Ordinary Differential Equation (ODE) solver for Tcl. Handles both stiff and non-stiff sets of equations; does time-evolved initial value problems and root finding. Based on the popular Lawrence Livermore solver LSODE.

This project and all source code has moved to GitHub, see https://github.com/virtualcell

This project aims to model parasites in order to assist in the analysis and prediction of their behavior.

WEST (Wind Energy Simulation Toolkit) is a wind simulation application. It can be use to obtain high resolution results at various altitudes.

YAFEMS (Yet Another Finite Element Method Solver) is a FEM solver for Linux and WIndows that reads a MED mesh file produced by Salome (http://www.salome-platform.org/) with certain groups created into the mesh, and with the help of an input text file (.yaf), performs a 3D or 2D plane stress or plane strain analysis and creates results in plain text format and in MED format. This way a complete analysis can be carried inside Salome, where a mesh file can be created, exported and read by YAFEMS with the help of a .yaf input file and post-processed within Salome using ParaView. New in v0.4 - More performance boost due to the implementation of the Cuthill-McKee algorithm.

astronx simulates the motion of mass-centres in cartesian space. The mass-centres interact solely through gravity. astronx uses the Bulirsch-Stoer extrapolation algorithm with adaptive stepsize to integrate the newtonian equations of motion.

User friendly interface for calculating electronic properties in graphene-like ribbons. The programs uses the tight binding approximation and mean field Hubbard model to predict electronic properties of graphene-like nanoribbons. See Discussion to ask questions or details Update: New versions of this program will be known as quantum-honeycomp

Monte Carlo implementation for the "Mobile Charge Densities in Harmonic Oscillators" (MCDHO) Molecular Force Field for Numerical Simulations of Biological Systems

An object-oriented Fortran 2003 programming environment for implementing numerical environmental simulation models, including climate and weather prediction models.

A collection of Fortran 2003, 90 and 77 routines, modules and programs for automatic simulation based global constrained optimisation. The initial application is for FE simulation of elasto-plastic buckling of steel rods aimed at tuning the hardening model. Unix shell scripts are used extensively. High concurrency is achieved with parallel multi-start global search and with parallel MPI FE. Powell's BOBYQA or LINCOA are used (not included in this package). Automatic mesh generation of 3D cylinders is provided + automatic boundary conditions, all via Fortran and shell scripting.

a library which i hope to write to compute high precision aerodynamic and electrodynamic equations
