How to calculate and write out transient drag / lift coefficient in OpenFOAM 2.2.1?
It seems that a keyword functions containing forces and forcesCoeffs should be added at the end of controlDict.
Is there any tutorial to give a typical example, and what's the meaning of each entry.
These two are founded on OpenFOAM forum.
i use execFlowFunctionObjects but i have this problem
Time = 0.0008
Selecting incompressible transport model Newtonian
Selecting LES turbulence model oneEqEddy
Selecting LES delta type smooth
Selecting LES delta type cubeRootVol
--> FOAM Warning :
From function cubeRootVolDelta::calcDelta()
in file cubeRootVolDelta/cubeRootVolDelta.C at line 52
Case is 2D, LES is not strictly applicable
Lift and drag
There's in OF a function object that allows to evaluate lift and drag?...not coefficient.
Thank's in advance for your attention
type this inside functions () in controlDict
patches (//patches of wall you are calculating);
rhoName rhoInf;//for incompressible
rhoInf 1.2; // Reference density, fluid
CofR (0 0 0); // Origin for moment calculations
You can find in tutorials/incompressible/pimpleDyMFoam/wingMotion/
