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...

f3dmlib is a FEM library that can read, write and analyse 3D tetrahedral meshes, minimize a given functional, and refine the resulting meshes. The minimization is parallelized with OpenMP. Three main features in unstable 1.8.x version (available via GIT): quadratic elements, periodic boundary conditions, and the solver for scalar and electromagnetic wave equations. f3dmgeom is a collection of a few simple tools for creating surface meshes for tetgen. It can handle simple geometries only.

Coffee-Physics is a minimalist physics engine written in CoffeeScript that favors approachable, creative-coding workflows over heavyweight simulation frameworks. It models motion with a particle system and uses simple constraints and behaviors—such as gravity, attraction/repulsion, drag, and springs—to create believable movement with very little code. The design is intentionally composable: you attach behaviors to particles or groups and let the update loop integrate positions, producing...

...Its features include simulation in 1D, 2D, and 3D Cartesian coordinates, distributed memory parallelism on any system supporting the MPI standard, portable to any Unix-like system, variuos dispersive ε(ω) models, CPML absorbing boundaries and/or Bloch-periodic boundary conditions, and arbitrary material and source distributions. GMES officially stands for GIST Maxwell’s Equations Solver.

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.

Discrete Dipole Approximation Project, is a software package designed to solve the Discrete Dipole Problem by the Discrete Dipole Approximation (DDA) method. This software is desgined to be plugin operated allowing for easy implimincation of new solver methods to improve the efficienty of the code. The plugin support also allow the program to write its output in multiple formats and structures defined by plugins.

A reactor solver which uses stochastic particle methods to model particle population balances. This code is developed by the CoMo group in the chemical engineering department at the university of Cambridge (como.cheng.cam.ac.uk).

MRCWA - Multilayer Rigorous Coupled Wave Analysis is a fast, flexible optical grating solver. It calculates an exact solution to the Maxwell equations for the diffraction of light from an optical grating with arbitrary profile and materials.

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.

Matho is a OS Independant Application and API for mathematical operations, features include curve sketching, calculus, iterative formulae, algebra solver, 2d/3d geometry and mechanical and statistical functionality.

OpenPL is a software interface to physics hardware, defaulting to a software constraint solver to make use of the CPU in the absence of a hardware implementation such as Aegia PhysX processor or Nvidia's HavokFX SLI implementation.
