CBMPy supports user interaction via: - interactive console or as a library for advanced use - GUI, visual representation of the model, analysis methods - a SOAP based webAPI exposes high level functionality via web services
Open Source CFD
REEF3D is an open-source computational fluid dynamics program. With a strong focus on hydraulic, coastal, offshore and environmental engineering, as well as Marine CFD, the use of the level-set method enables it to calculate complex free surface flows. The model is implemented in highly modular C++ and the source code is available under the GPL license. The MPI library is used for parallelization, making REEF3D the perfect tool for high performance CFD calculations. The model is currently under development and additional features are added in a fast pace. The goal is to make the full transition from a research tool to a powerful engineering software.

Open source 3D Matlab Isogeometric Analysis Code
Isogeometric analysis (IGA) is a fundamental step forward in computational mechanics that offers the possibility of integrating methods for analysis into Computer Aided Design (CAD) tools and vice versa. The benefits of such an approach are evident, since the time taken from design to analysis is greatly reduced leading to large savings in cost and time for industry. The tight coupling of CAD and analysis within IGA requires knowledge from both fields and it is one of the goals of the MIGFEM is to provide a simple-to-understand IGA FEM code. The work is funded under the FP7 Initial Training Network Funding under grant number 289361 'Integrating Numerical Simulation and Geometric Design Technology.' If you use this code or inspired by it please cite the following reference in your work: VP Nguyen, C Anitescu, S Bordas, T Rabczuk.

Polycrystal generation and meshing.
Neper is a software package for polycrystal generation and meshing. It can deal with 2D and 3D polycrystals with very large numbers of grains. Its main features are: - Generation of polycrystals from (experimental) morphological properties; - Generation of multiscale microstructures; - Generation of periodic or semi-periodic microstructures; - Meshing into good-quality elements; - Meshing with cohesive elements at interfaces; - Visualization and analysis of the tessellations and meshes. Neper is built around three modules: generation, meshing and visualization. All the input data are prescribed non-interactively, using command lines and / or ASCII files. Neper can be compiled and run on any Unix-like system.
