stellarics
Inverse Compton emission from heliospheres of sun and stars
Cosmic ray electrons scatter on the photon fields around stars, including the sun, to create gamma rays by the inverse Compton effect. This program computes the spectrum and angular distribution of this emission. The software also includes general-purpose routines for inverse Compton scattering on a given electron spectrum, for example for interstellar or astrophysical source modelling. For further information see these publications: http://arxiv.org/abs/astro-ph/0607563, http://arxiv.org/abs/0801.2178, http://arxiv.org/abs/1104.2093, http://adsabs.harvard.edu/abs/2013NuPhS.239..266O and this conference presentation: https://confluence.slac.stanford.edu/download/attachments/130879399/poster_symposium_sun_2012.pdf and the corresponding conference paper http://arxiv.org/abs/1307.6798 2017 June 16: now available from gitlab https://gitlab.mpcdf.mpg.de/aws/stellarics which will be used for future develpments. -

MIST
A MATLAB toolbox to simulate optical systems
Modal Interferometer Simulation Tool (MIST) is a MATLAB toolbox that can simulate arbitrary resonant optical systems in the paraxial beam approximation. It allows the user to define any optical setup (composed typically of laser sources, mirrors, lenses, electro-optical modulators and detectors) and to compute the static laser field at any point. It uses a Hermite-Gauss modal decomposition to simulate diffraction limited optics. This tool is being developed mainly for simulation of large scale interferometers with resonant cavities used for the detection of gravitational waves. Subscribe to the mailing list for updates and news. If you use MIST in your own simulation work, please cite is as G. Vajente, "Fast modal simulation of paraxial optical systems: the MIST open source toolbox" Classical and Quantum Gravity 30, 075014 (2013) -

MaxFEM
Software for electromagnetic simulation
MaxFem is an open software package for electromagnetic simulation by using finite element methods. The package can solve problems in electrostatics, direct current, magnetostatics and eddy-currents. Since version 0.4.0, MaxFEM requires Python 3. We have moved the installers to the MaxFEM website (see below). In order to improve MaxFEM, we will require you to fill out a simple form before downloading them. -

qutoss
sandbox particle simulator that obeys schrödinger's equation
Enjoy bizarre Quantum Mechanics animations by throwing a 2D particle in arbitrary environments. There is infinite freedom in customizing the potentials: draw out absurd terrains, or opt for standard experiments such as double-slit. The project's purpose is to aid the user in building intuition for the peculiar workings of the quantum realm. As such, it aims to be user-friendly and does not require prior knowledge of QM. Currently only available for macOS and Windows users (Linux version will be uploaded in the future). Created with Qt and OpenGL. -

VASPMO
Visualization of wavefunctions calculated by VASP (New release: v0.41)
VASPMO aims at visualizing wavefunctions (or molecular orbitals) from VASP calculations. It reads VASP's output files PROCAR and CONTCAR, and exports an *.out file in Gaussian's output format, which can be visualized by many popular visualization tools, such as JMol, Molekel, Chemcraft, Gabedit and Molden, etc. These tools can further generate *.cube files, which can be visualized by an even wider range of softwares. 读入VASP计算得到的PROCAR和CONTCAR文件，输出Gaussian结果文件。该文件能够被常用的量子化学可视化软件（如Molekel、Chemcraft、Gabedit、Molden和JMol等）读取，进而绘制和观看体系的分子轨道。有些软件还能导出 cube文件（如Chemcraft和Molden等），从而又能被很多支持cube格式文件的可视化软件所识别。 -

CEFT/E-Space
This work did not begin with a theory. It began with a question.
Preface: On the Road to Co‑Emergence This work did not begin with a theory. It began with a question — a displacement — and the long, recursive response that followed. For years, physics, philosophy, computation, and consciousness studies have circled the same paradoxes: How can something arise from nothing? Why does the vacuum have structure? Why do infinities appear where our theories should be smooth? Why does awareness feel irreducible? These questions were not failures of mathematics. They were failures of ontology — the quiet assumption that space is a container, that the vacuum is empty, that structure sits in something rather than creating the very medium it appears to inhabit. This manuscript emerged from the decision to challenge that assumption. It began with our lattice experiments — a simple grid, pulsing, collapsing, reorganising — and the realisation that the lattice was not sitting in space. It was making space. -

Cambridge Rocketry Simulator
Simulate high power rocket flights with splash down plots
This software allows you perform six degree of freedom simulations of High Power Rocket (HPR) and model rocket flights. Parachute descent is also simulated. 3D flight trajectories are produced as well as detailed tabular flight data. Running in Monte Carlo mode allows generates multiple possible flight paths and splash down plots, indicating the probability of landing in an area.
