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 |
