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. For incompressible solvers (example: simpleFoam), this field is actually the pressure normalized by constant fluid density. To get true pressure, you need to multiply by the density of your fluid in post processing. For compressible solvers, p is the true 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 |
