Adaptive Simulated Annealing (ASA) is a C-language code that finds the best global fit of a nonlinear cost-function over a D-dimensional space. ASA has over 100 OPTIONS to provide robust tuning over many classes of nonlinear stochastic systems.

...CalculiX is most popular FEA open-source package (like Code-Aster and Elmer-FEM). it is comparable in features with most known commercial packages like ANSYS, NASTRAN, Abaqus, etc. Good for structural, mechanical, thermal and fluid applications (trusses, plates, frames, shells, solid bodies). It has powerful nonlinear capabilities (including tension/compression only material like concrete) and most types of analysis (modal, thermal, buckling, coupled, etc) . See home page at http://www.dhondt.de New versions can be obtauned here: http://calculixforwin.blogspot.com/2015/05/calculix-launcher.html PS Appimages for Scilab, wxMaxima and GNU Octave were added

...Curve fitting (Linear and Nonlinear). 8. Numerical integration (Undetermined Coefficients, Newton-Cotes, Romberg). 9. Ordinary differential equations (Euler, Runge-Kuta).

Impact is an explicit Finite Element Program Suite which simulates dynamic impact events. It has a range of elements, contact handling and different material laws. Models can be created, solved and analyzed with the included pre- and postprocessor. Impact is based on an Explicit Time stepping algorithm. These kind of codes are used to simulate dynamic phenomena such as car crashes and similar, usually involving large deformations.

ACADO Toolkit is a software environment and algorithm collection for automatic control and dynamic optimization. It provides a general framework for using a great variety of algorithms for direct optimal control, including model predictive control, state and parameter estimation and robust optimization. ACADO Toolkit is implemented as self-contained C++ code and comes along with user-friendly MATLAB interface. The object-oriented design allows for convenient coupling of existing optimization...

H2O is a collection of C routines and applications designed for the optimization of multi-reservoir and multi-period hydrothermal power production scheduling. H2O is built upon nonlinear network algorithms and heuristic techniques for higher efficiency.

The Delta code is an nonlinear aeroelastic solver written in fortran 90. At the moment only vortex lattice aerodynamics is available but the hope is for a higher fidelity aerodynamic model to be developed for use in the current code. Linux and Unix.

RealPaver is a modeling language for solving mixed-integer nonlinear constraint systems.
