Hello all

Currently I'm trying to simulate the Karman vortex shedding of a 2D geometry compound of three consecutive cylinders. (image attached)

I've been investigated regarding the coefficients Aref and Lref which must be given in the function forceCoeffs. The Following [Post 1] make it clear to what values should be given for the coefficients, however, it is not clear to me what value should be given in my case. Please find attached the image.

How this coefficients are used in openfoam ?
How could I get the lift coefficient for each of the 3 geometries ? Is this even possible ? How would be interpreted the overall lift coefficient ?

Thanks in advance.
