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.
  • 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 Graph.
  • 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.
  • 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.
  • 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.
  • 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.
  • vis | visualisation software.
  • weak | weak gravitational lensing tool.
