Keywords

This is a list of keywords used to describe software throughout this site.

• 1D,2D,3D | runs in 1,2 and/or 3 dimensions.

• amr | allows for adaptive mesh refinement.

• analysis | analysis software.

• cmb | computes cosmic microwave background (cmb) anisotropy, polarization and matter power spectra.

• cosmo | runs in a cosmological mode. That typically means that it will work within an expanding FRW background. Coordinates are then usually co-moving.

• direct | solves gravity via direct summation which scales as .

• fake | generates fake astronomical data (e.g. a fake astronomical image).

• genrelativity | solves GR equations of motion.

• grape | uses a Grape board for hardware acceleration. Typically used for direct summation gravity calculations (see also direct).

• gravity | solves Newton's equations of motion. For General relativity see genrelativity. If only this keyword is present, this assumes it solves only for external static fields. For dynamic self-consistent fields see selfgravity.

• grid | uses grid-based simulation data. See e.g. here for more information.

• gridpolar | uses a polar grid.

• gridgeom | can handle complex grid geometries.

• ic | generates initial conditions (ic) for simulations.

• interact | runs in an interactive mode.

• lensing | gravitational lensing tool.

• mhd | solves magneto-hydrodynamic equations.

• non-para | is “non-parametric” meaning that it uses a model with more parameters than there are available constraints.

• parallel | will run on multiple processors.

• parallelshare | will run on multiple processors. Requires a shared memory machine.

• particle | uses particle-based simulation data. See e.g. here for more information.

• plasma | simulates physical conditions within an astrophysical plasma.

• python | accepts python scripts.

• radxfer | includes radiative transfer physics.

• relativity | solves SR equations of motion.

• selfgravity | can calculate the force of gravity between individual fluid elements.

• shearing | can perform shearing box calculations. See e.g. here for more information.

• spectra | calculates spectra of astrophysical plasmas.

• sph | smoothed particle hydrodynamics. A particle method for solving the Euler equations. See here for a brief review and further reading.

• starform | includes a prescription for turning gas into stars.

• starevolve | includes physics for stellar evolution.

• strong | strong gravitational lensing tool.

• thermonuclear | includes physics for thermonuclear reactions.

• tree | uses a tree method to calculate forces.

• vis | visualisation software.

• weak | weak gravitational lensing tool.

• UK SPH Forum | UK SPH Forum
