OpenFOAM is distributed with a set of utilities that
perform specific post-processing tasks, as listed below.
Post-processing the velocity field
Co
Configurable graph drawing program
divU
Calculates and writes the divergence of velocity field U at each time
enstrophy
Calculates and writes the enstrophy of velocity field U at each time
flowType
Calculates and writes the flowType of velocity field U at each time
Lambda2
Calculates and writes the second largest eigenvalue of the sum of the square of the symmetrical and anti-symmetrical parts of the velocity gradient tensor, for each time
Mach
Calculates and writes the local Mach number from the velocity field U at each time
magGradU
Calculates and writes the scalar magnitude of velocity field U at each time
magU
Calculates and writes the scalar magnitude of the gradient of the velocity field U for each time
Pe
Calculates and writes the Pe number as a surfaceScalarField obtained from field phi for each time
Q
Calculates and writes the second invariant of the velocity gradient tensor for each time
streamFunction
Calculates and writes the stream function of velocity field U at each time
Ucomponents
Writes the three scalar fields, Ux, Uy and Uz, for each component of the velocity field U for each time
uprime
Calculates and writes the scalar field of uprime () at each time
vorticity
Calculates and writes the vorticity of velocity field U at each time
Post-processing the stress field
R
Calculates and writes the Reynolds stress R for the current time step
Rcomponents
Calculates and writes the scalar fields of the six components of the Reynolds stress R for each time
stressComponents
Calculates and writes the scalar fields of the six components of the stress tensor sigma for each time
Post-processing at patches
patchAverage
Calculate average of fields over all patches
patchIntegrate
Integrates fields over all patches
Post-processing at a wall
checkYPlus
Calculates and reports yPlus for all wall patches, for each time in a database
wallGradU
Calculates and writes the gradient of U at the wall
wallHeatFlux
Calculates and writes the heat flux for all patches as the boundary field of a volScalarField and also prints the integrated flux for all wall patches
wallShearStress
Calculates and writes the wall shear stress for the current time step
yPlusLES
Calculates the yPlus of the near-wall cells for an LES
Other post-processing
engineCompRatio
Calculate the geometric compression ratio. Note that if you have valves and/or extra volumes it will not work, since it calculates the volume at BDC and TCD
postChannel
Post-processes data from channel flow calculations
ptot
For each time: calculate the total pressure
sample
Sample field data with a choice of interpolation schemes, sampling options and write formats
sampleSurface
Surface sampling. Runs in parallel (but does not merge points)
wdot
Calculates and writes wdot for each time
writeCellCentres
Write the three components of the cell centres as volScalarFields so they can be used in postprocessing in thresholding
