GeographicLib is a small set of C++ classes for converting between geographic, UTM, UPS, MGRS, and geocentric coordinates, for gravity (e.g., EGM2008), geoid, and geomagnetic field (e.g., WMM2010) calculations, and for solving geodesic problems. For documentation, visit https://geographiclib.sf.io
Cantera is a suite of object-oriented software tools for problems involving chemical kinetics, thermodynamics, and/or transport processes. It can be used from MATLAB, Python, C++, or Fortran.
A shared memory parallel sparse matrix library including Sparse BLAS.
librsb is a library for sparse matrix computations featuring the Recursive Sparse Blocks (RSB) matrix format. This format allows cache efficient and multi-threaded (that is, shared memory parallel) operations on large sparse matrices. The most common operations necessary to iterative solvers are available, e.g.: matrix-vector multiplication, triangular solution, rows/columns scaling, diagonal extraction / setting, blocks extraction, norm computation, formats conversion. The RSB format is especially well suited for symmetric and transposed multiplication variants. On these variants, librsb has been found to be faster than Intel MKL's implementation for CSR. Most numerical kernels code is auto generated, and the supported numerical types can be chosen by the user at build time. librsb implements the Sparse BLAS standard, as specified in the BLAS Forum documents.
IRBEM-LIB provides routines to compute magnetic coordinates for any location in the Earth's magnetic field, to perform coordinate conversions, to evaluate geophysics/space-physics models, and to propagate orbits in time.
The GetData library provides an API to interface with Dirfile databases. The Dirfile database format is designed to provide a fast, simple, scalable format for storing and reading binary, synchronously-sampled, time-ordered data.
Development of new data assimilation techniques for ocean models
Fast Gauss Transform Implementation Evaluate the sum of N Gaussians at M points
ChesROMS is developing a ROMS model of the Chesapeake Bay to help in the prediction of Harmful Algal Blooms. We hope to catalyze a new method of community modeling with involvement beyond the core researchers of the ChesROMS project.
This project contains several libraries written in Fortan 77, Matlab and C++, pertinent to computational fluid dynamics, boundary element methods, finite and spectral element methods, numerical methods, and C++ programming in science and engineering.
1-dimensional Eulerian Vlasov-Maxwell solver, used primarily for studies of kinetic effects in plasma waves and for stimulated Raman scattering.
the MMM to HADDOCK tool
MISHAP is the open-source MMM in silico simulated spin label to HADDOCK program. MISHAP aims to take spin labelled proteins and the distance distributions between labels from in silico (MMM) calculations or experimental data (from pulsed electron-electron double resonance experiments which have been analysed with DeerAnalysis) and pass them to the biomolecular docking program HADDOCK as docking restraints.

This script fills in a two dimensional surface with an unbroken, non-overlapping path. The path direction is random, so one can imaging a chess board filled with dominos, with the constraint that the layout of the dominos is complete (board is filled) an
