[OpenFOAM] Lift and drag vs distance

ufocfd · July 22, 2021, 06:06

Anyone done paraview scripting for lift and drag profiles vs distance for an aerodynamic body? Eg drag profile along the length of a body. It requires taking multiple slices and then integrating over the slices. Preferably including both viscous and pressure components of the lift and drag.

I managed to get this sorted (kind of) by clipping the surface of interest, and integrating on the clipped surface, and write the integrated result to an output file. Then using the paraview feature to "record test" created an XML file to repeat the process several times, changing the clip location each time. Its a bit of a fiddly process but it worked for the pressure force integration over a body.
