MiXiM is a simulator for wireless and mobile networks using the OMNeT++ simulation engine.

A parametric, feature-based, sketch-driven 3D CAD application, built around a geometrical constraint solving engine. Project is in early development stage. The FreeSG library (http://freesg.org/) is required.

This code is a dedicated Kinetic Monte Carlo (KMC) algorithm which simulates a model of the post-translational Kai circadian clock. The code allows you to simulate the Kai system at the level of individual KaiC hexamers and monomers and explicitly tracks the turnover of every ATP nucleotide. Apart from ATP hydrolysis, all reactions obey detailed balance. The application of the code is described in our article titled "A Thermodynamically consistent model of the post-translational Kai circadian clock", which is freely available at the open access journal PLOS Computational Biology: https://doi.org/10.1371/journal.pcbi.1005415 *UPDATE* We made a fully reversible version of our model, including the inverse reactions for ATP hydrolysis. This makes it possible to run the model at thermodynamic equilibrium. This version of the model can be downloaded under KMC_KaiC_Rev.zip. If you like to use our model for your own research, please cite our PLoS Computational Biology paper.

Critterding is a "Petri dish" universe in 3D that demonstrates evolving artificial life. Critters start out with completely random brains and bodies, but will automatically start evolving into something with much better survival skills.

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.'

A package for transient and steady state simulation of organic solar cells.

The program does nmr product operator calculations for one, two, three and four spins. Receiver phase cycling is possible in conjunction with pulse phase cycling to simulate coherence pathway selection. An extensive manual and help files are included. Currently running under Linux and Windows.

GLUI is a GLUT-based C++ user interface library which provides controls such as buttons, checkboxes, radio buttons, and spinners to OpenGL applications. It is window-system independent, using GLUT or FreeGLUT.

A real-time graph plotter. While your application is computing and logging results to a CSV file using the LiveGraph Writer API, the plotter lets you visualise and monitor the results live - by instantly plotting charts and graphs of the data.

http://loto.sourceforge.net/ hosts 4 projects of free software related to materials science and physics. They are loto, feram, compasses and xtalgrowth.

CAMFR (CAvity Modelling FRamework) is a fast, flexible, friendly full-vectorial Maxwell solver. Although it can tackle general electromagnetic problems, its main focus is on applications in the field of photonics.

This application can produce input files of various applications for density functional theory (DFT) calculations via user-friendly parameter adjustment using three-dimensional computer graphics (3DCG) and graphical user interfaces (GUI). Input-file conversion between different applications is also possible. Now C-Tools supports the three file formats for DFT codes, xTAPP, OpenMX, RSDFT, VASP and Quantum ESPRESSO(PWscf).
