GRAMPC is a nonlinear MPC framework that is suitable for dynamical systems with sampling times in the (sub)millisecond range and that allows for an efficient implementation on embedded hardware. The algorithm is based on an augmented Lagrangian formulation with a tailored gradient method for the inner minimization problem. GRAMPC is implemented in plain C with an additional interface to C++ and MATLAB/Simulink. The basic structure and usage of GRAMPC are described in the documentation...

Puff is an atmospheric dispersion model using a lagrangian particle-tracking method, used primarily for simulating volcanic ash cloud trajectories.

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...

alleged to the video 'tutorial' "the Mechanics and its Simulation". Simulation with Lagrangian method, both symbolic, and by numerical derivation. All well-grouped in folders. there is also a 'review' in 3 demos of the Newtonian dynamics: mass-spring systems. most of progs are written in C, with use of SDL lib to display simple graphics and have real-time interactivity. As to programming complexity, it's very simple... this all aims at classical physics simulation in a simple but efficient way...

2D simulation game using exlusively Lagrangian equations of motion. It's a 2D motocross game similar to X-Moto, ActionSupercross and such. Some stability issues persist but mostly it's good already. I shall compile it soon for Windows: one of the problems is that Windows compilers must periodically be reinstalled, and that's annoying. Using Lagrangians in games is not a well documented thing, but it allows to achieve exellent results in very little time, soon after a good parametrization...

CTruck 2D is a 2D, oldstyle, physically realistic 2D truck game. Predecessor of the CTruck3D vehicle simulator series. I wrote it from zero in C (+OpenGL&GLUT). It has ascii-art and nice graphics version, and a special funny version It's a very basic thing: there are free rigid bodies and springs with strong attenuation/damping. It's very simple and very short code, and collisions of bodies with ground are good and stable. A good simulation of this kind, however requires Lagrangian...
