# OpenFOAM guide/Table of common fields

From OpenFOAMWiki

< OpenFOAM guide(Redirected from Uguide table of fields)

This table should give a list of the field names commonly written by the OpenFOAM-Solver.

It was inspired by the discussion What's the meaning of variables in the computed results in the Forum:

Filename | Description | Dimension |
---|---|---|

U | Velocity | |

U_0 | Velocity at previous timestep (needed for restarting higher order time-stepping schemes) | |

phi | Flow through cell faces. Depends on whether the solver is for incompressible or compressible flow. | incompressible flow: compressible flow: |

p | Pressure | |

epsilon | Turbulence dissipation rate | |

k | Turbulence kinetic energy | |

rho | Gas density | |

alpha | Dispersed phase volume fraction | (Dimensionless, usually within the interval [0, 1]) |

Theta | Granular temperature |
