TFEL/MFront introduces DSLs based on C++ to handle material knowledge
The TFEL library is a collaborative effort of the French Atomic Commission and Électricité de France. TFEL mostly includes the MFront code generator. MFront is based on C++ and provides several domain specific languages which were designed to simplify the implementations of new material properties, mechanical behaviours and simple material models. A particular focus was made on mechanical behaviours which are by essence more complex and may have significant impact on the numerical performances of mechanical simulations. Various performance benchmarks show that the code generated using MFront is in most cases on par or better than other implementations, generally written in Fortran. For mechanical behaviours, MFront introduces interfaces for various finite element or FTT solvers (Cast3M, Code-Aster, ZeBuLoN, Abaqus, Europlexus, AMITEX_FFT, etc..). The authors hope that it will prove usefull for researchers and engineers, in particular in the field of solid mechanics.

Real-time interactive 3D graphics API for scientific simulations
OpenFrames is an Application Programming Interface (API) that provides the ability to add interactive 3D graphics to any scientific simulation. A simulation developer can use OpenFrames to specify what they want to visualize, without having to know any details of computer graphics programming. Visualizations created using OpenFrames are cross-platform, hardware accelerated with OpenGL, and designed specifically to minimize computational overhead. They can be embedded within an existing GUI framework (e.g. Qt, wxWidgets, Winteracter) or created in independent OS-native windows. The OpenFrames API itself is written in C++, and bindings are available for C and Fortran.

Time-dependent simulation of open and closed quantum systems
WavePacket is a program package for numerical simulation of quantum-mechanical wavepacket dynamics for distinguishable particles. It can be used to solve one or more (i.e. coupled channels) time-independent or time-dependent (linear) Schrödinger and Liouville-von Neumann-equations. Optionally accounting for the interaction with external electric fields within the semiclassical dipole approximation, WavePacket can simulate modern experiments using ultrashort light pulses in photo-induced physics or chemistry. WavePacket is especially suitable for teaching of quantum mechanics as well as for research projects in physics, chemistry, and scientific computing. The present C++ version is an object-oriented rewrite of the existing Matlab version aiming to be more flexible. In particular, the goals are easy handling of open and closed systems and support for unusual setups.
