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...

Libraries for integration of atmospheric trajectories. Includes a basic trajectory integrator, contour advection codes and semi-Lagrangian tracer simulations.

Paris, or ParisSimulator, is a PArallel Robust Interface Simulator. It combines VOF and Front-Tracking to create simulations of interfacial fluid flow, such as droplet bubbles or waves. It computes complex flows such as fast atomizing jets and has a Lagrangian particle option.

These Matlab scripts illustrate the numerical solution of two one-dimensional tensile rods equipped with integro-differential and strain-gradient constitutive laws by means of classical Hermitian and Lagrangian finite element discretizations, B-spline finite element discretizations and C∞ generalized finite element discretizations.

Handles Hexahedral, Tetrahedral, Quadrilateral, and Triangle meshes. Lagrangian, Hierarchic, and Monomial finite elements. Interface to PETSc solvers, adaptive mesh refinement, and extreme portablility.

This matlab package, SADoRe, accompanied by the paper Q. Zhang 2012 CMAME ``Highly Accurate Lagrangian Flux Calculation via Algebraic Quadratures on Spline-Approximated Donating Regions,'' is for donating region construction and Lagrangian flux computation in two-dimensional space. This package depends on the SplineGauss package by Sommariva and M. Vianello, following the following steps to use SADoRe: (1) Download SplineGauss from http://www.math.unipd.it...

This code holds all the matlab files necessary to run a 2D isogeometric code for elastostatic analysis. For more guidance, it is probably a good idea to have a look through the code repository, and more recent updates to the code may also be present here. The main idea is that instead of using conventional Lagrangian polynomials to discretise the unknown fields and geometry (using the isoparametric concept), the basis functions that are used in Computer Aided Design (CAD) are used instead...

The polymer model called FENE is simulated in a Lagrangian frame of reference in various flow types such as turbulent flow, laminar shear flow, etc. A Qt-based GUI is created in this project to animate the dynamics.
