Dear all,

If vacuum boundaries are used, extra terms are added to the particle
acceleration. In the case of comoving integration, OmegaMatter0 is the
defining parameter (gravtree.c, line 290). And in the case of physical
coordinates, it's OmegaLambda: (gravtree.c line 331). Can anyone
enlighten me about the exact origin is of these terms? Thanks in advance!
