there is a problem with the hypothesis of long range field anisotropy that creates a body spacing anisotropy because all the rest of the square is evenly spaced. Why would an anisotropic field appears ?
heavy work :
light work :
attempt with 1/r3 repulsion vector intensity makes no changes. This goes along that the the field anisotropy must be rendered
Note: the issue is not dependant on the siee (8000 or 200000 bodies Note: the issue is not dependant on the theta of the barnes hut (try to lower theta to 0 at the end has no effect) A programming issue ?
the problem is solved when NbRoutine == 1. So the problem is concurrency provoked
solved : commit log !
startIndex := (i*sliceLen)/nbRoutine
