Print forces acting on kinematic parcels

ffran · November 14, 2022, 09:49

Hi,
I am working with parcels belonging to kinematic clouds and I was wondering if there was an easy way to output the forces acting on each parcel. From what I can see in KinematicParcel.C, the forces are computed in the calcVelocity() method, which takes a templated TrackData object (td) that I can't seem to find anywhere. Then the force list is taken as td.cloud().forces(), which is of type cloudType::forceType, which in turn seem to be somehow related to particleForceList. My question is: given a parcel p in a cloud, how can I access each force and output it (e.g. as a CSV file)? Seemingly only the sum is available in OF, and not directly accessible from outside TrackData. If you have any resources regarding the workflow of LPT in OpenFOAM, those would be very welcome too.

Kind regards,
Francesco
