Nifty Sim is a high-performance nonlinear finite element solver, developed at University College London. A key feature is the option of GPU-based execution, which allows the solver to significantly out-perform equivalent commercial packages.

CFD2D is open source software for Linux for solving the non-dimensionalized incompressible Navier-Stokes equations (NSE) inside an arbitrary two-dimensional domain inscribed in a unit square with Dirichlet and "do-nothing" boundary conditions. The space discretization is based on Finite Element Method (FEM) using an approximately uniform triangular mesh. The two choices of FE spaces are offered, these are of the so called MINI-element and of the Taylor-Hood element. The first element consists of continuous piecewise linears with a cubic bubble function for the velocity field, and the second of continuous piecewise quadratics for the same. ...

WOLFSIM is a Finite-Difference Time-Domain electromagnetic simulator, designed to be easy to use but still very powerful, developed and maintained by researchers at North Carolina State University. It's features include: -1D, 2D, and 3D structures that are periodic in 1 or 2 dimensions -Materials that are anisotropic in permittivity and conductivity -Obliquely incident sources -Built-in vectorial (i.e. full polarization) near-to-far-field transformation See these publications for full details on the algorithm: http://www.ece.ncsu.edu/oleg/files-wiki/6/62/SPIE_12_Miskiewicz_wolfsim3D.pdf http://www.ece.ncsu.edu/oleg/files-wiki/1/13/OptExpress07_OH.pdf

3D vehicle simulator in which vechicle's configuration as a whole (articulated body) , is represented by a 'vector' of generalised coordinates. so concepts like usual position and orientation of main body and wheels is all defined by the generalised coordinates.Using Lagrangian dynamics, theese coordinates are evolving in time in a realistic manner according to F=ma but as if there were also all constraint forces concretasing the presence of joints: hinge, prismatic, rigid connection, etc. all derivatives are done with finite differences, so it's all simple. in 3 videos I explain all the mechanics and its simulation up to this simple but pow method.Pure Lagrangian mechanics until now has not been used much or at all,in simulation videogames,but i decided to try it because it was promising, very simple compared to the fnal results, and there was not much docu on its use in simulation games: this lack was completed now. ...

Wavefront is a programme for simulating 2D acoustic systems, with a particular emphasis on determining wavefront shapes at the mouths of horns. It accepts CAD drawings in DXF format and produces animated displays of wave propagation as well as exporting various data as text files. It is GPL software and runns on Linux and Windows.

The Virtual Geoscience Workbench for discontinuous systems is a computer software environment for modelling. We have made the combined Finite-Discrete Element Method (FEMDEM) the core of our solids technology.

Geometric modeling, mesh generation and definition of boundary conditions for the numerical solution PDE problems by finite element and finite volume methods.

The VSC_module is a plug-in to the commercial groundwater flow simulation with FEFLOW (Finite Element Flow System). The VSC_module is specialised on wetlands, and realises a variable storage coefficient for saturated transient flow.
