To Whom it May Concern,
I'm trying to determine angles in elastic collisions, which I get from the momentum vector of the parent particle's prestep point and the momentum vector of the secondary particle's track (from the function GetSecondaryInCurrentStep()). I specify the parent prestep point's process to be "hadElastic", however the momentum of the parent from prestep to poststep doesn't change, which confuses me.
How can I get the momentum direction of the parent particle right before an elastic collision with a secondary particle?
