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.

This compact function parser module written in Fortran95 is intended for applications where a set of Fortran-style mathematical expressions is specified at runtime and is then evaluated for a large number of variable values.

User friendly interface for calculating electronic properties in graphene-like ribbons.

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

This program allows to perform a structural cluster analysis of atomic trajectories obtained, e.g., from molecular dynamics simulations. At variance with other approaches, it is possible to analyse also processes in solution, e.g., chemical reactions in liquid water, since the distance metric is based on a Permutation Invariant Vector (PIV) that is symmetric under exchange of identical atoms or molecules, including on the same footing both solute and solvent degrees of freedom. The approach is general and the definition of PIV only requires to specify the range of interatomic distances that is relevant for the process under study. Alternatively, also the SPRINT topological coordinates can be employed, that are particularly suited for nanostructures. The output is a partitioning of the trajectory into a few structural clusters (i.e., sets of frames), allowing for simpler analysis and visualization. Please read and cite Gallet & Pietrucci, J. Chem. Phys. 139, 074101 (2013)

progrep is a command-line tool (Linux) to show live progress report, status & stats of a running simulation or compute job that executes a given number of iterations. It shows % completed, time remaining, time elapsed, number of threads, MPI_Rank(if any), CPU usage & speed (FPS). The FPS measures may be used in benchmarking, e.g. while optimizing HPC algorithms for performance. progrep supports both single-threaded and parallel (multicore/multinode - e.g. OpenMP/MPI) jobs. progrep can also report for jobs running on remote hosts, e.g. jobs running on Linux Clusters. progrep works in client-server model. The server can be installed in your simulation source code with only 4 extra lines (API). When the progrep command is invoked, it queries this server as a client. progrep does not interfere with or slow down your simulation when not invoked. Even when invoked, the overhead is insignificant. Out of the box, the API works with Fortran/C/C++ code. See Wiki/README for details.

pyPulsar is a program for simulation and fitting of solid-state NMR spectra. It provides scripting facilities using Python. (This project was not developed for a long time: It will be soon moved in a new project currently developed)

RANSFOIL is a console program to calculate airflow field around an isolated airfoil in low-speed, subsonic, transonic or supersonic regime by numerically solving the Reynolds averaged Navier-Stokes (RANS) equations using mature computational fluid dynamics (CFD) method. As postprocess results, the aerodynamic parameters of the airfoil, e.g., lift coefficient and drag coefficient, can be integrated from the airflow distribution near wall boundary. In addition, the coupling between airflow and heat transfer and the effect of surface roughness on near wall flow are considered by this program, it can be used for engineering calculation of the friction drag and heat transfer coefficients on airfoil surface. RANSFOIL reads coordinates data from a 1D XYZ file which describes the grid points or control points on airfoil as only input, then outputs grid and solution files in 2D PLOT3D format to record grid coordinates and airflow data and a report file to show aerodynamic parameters.
