    ransfoil

    console to calculate airflow around an airfoil based on RANS approach

    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...

    F3DM

    Finite Element Method on 3D Meshes

    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

    Coffee-Physics

    A simple, lightweight physics engine written in CoffeeScript

    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...

    RAtom

    solves nonlinear Kohn-Sham equation for the neutral atom.

    RAtom solves nonlinear Kohn-Sham equation for the neutral atom. The adaptive algorithm based on finite element method (FEM) is implemented. Discretization of the differential eigenvalue problem is done by finite element method with Lobatto polynomials as a basis functions. High order Gauss quadratures are applied in order to obtain the total energy of atom with absolut accuracy of 1E-6 hartree. Disctretization leads to generalized eigenvalue problem, which is solved by procedures from...
