Other post-processing utilities

Other post-processing utilities

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
enstrophy Calculates and writes the enstrophy of the velocity field U
flowType Calculates and writes the flowType of velocity field U
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
Mach Calculates and optionally writes the local Mach number from the velocity field U at each time
Pe Calculates and writes the Pe number as a surfaceScalarField obtained from field phi
Q Calculates and writes the second invariant of the velocity gradient tensor
streamFunction Calculates and writes the stream function of velocity field U at each time
uprime Calculates and writes the scalar field of uprime (∘ -----
  2k ∕3  \relax \special {t4ht=)
vorticity Calculates and writes the vorticity of velocity field U
 
Post-processing the stress field


stressComponents Calculates and writes the scalar fields of the six components of the stress tensor sigma for each time
 
Post-processing at patches


patchAverage Calculates the average of the specified field over the specified patch
patchIntegrate Calculates the integral of the specified field over the specified patch
 
Post-processing at a wall


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 specified times
yPlusLES Calculates and reports yPlus for all wall patches, for the specified times
yPlusRAS Calculates and reports yPlus for all wall patches, for the specified times when using RAS turbulence models
 
Other post-processing


dsmcFieldsCalc Calculate intensive fields (U and T) from averaged extensive fields from a DSMC calculation
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
execFlowFunctionObjects Execute the set of functionObjects specified in the selected dictionary (which defaults to system/controlDict) for the selected set of times
pdfPlot Generates an .obj file to plot a probability distribution function
postChannel Post-processes data from channel flow calculations
ptot For each time: calculate the total pressure
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
