A cross-platform, open-source, alternative to NIST REFPROP. Based on reference-accuracy equations of state and transport property correlations for refrigerants like Water, CO2, R134a, Nitrogen, Argon, Ammonia, Air, R404a, R410a, Propane and many others. A selection of secondary working fluid properties are also available. Can also make use of REFPROP when available. In addition, calculations for Humid Air Properties based on ASHRAE RP-1485 are provided.

- - - T H I S P R O J E C T M O V E D T O G I T H U B - - - A framework for the implementation of advanced real-time control systems which uses signal/block-based schematics (like Simulink) extended by several features like state machines and online-exchangeable sub-simulations. Besides, this framework properly handles multiple threads, their communication, allows to synchronise control systems to external events (e.g. variable timers or incoming network packages) and provides...

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.

ASCEND is a modelling environment and solver for large or small systems of non-linear equations, for use in engineering, thermodynamics, chemistry, physics, mathematics and biology. Solvers for both steady and dynamic (NLA & DAE) problems, are provid

Plouf is a set of algorithms that solve partial differential equations on sets of connected points. Emphasis is on fluid mechanics and plasma flows.

This project is a collection of FreeFEM++ scripts used to find numerical solutions of the free-surface incompressible Navier-Stokes equations. The boundary interpolations from a moving mesh are suitable for applying surface tension boundary conditions

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.

A repository of Direct Numerical Simulation codes (Full solutions of the Navier Stokes Equations in fluid dynamics) in various geometries using a mix of high-order finite-difference and spectral methods.
