Dear Markus,

Sorry about that. The ENGINE branch on hmenke's git account

has a fix for the bug. As I said, I recalled seeing something like it, and at that time we apparently fixed the problem (which I cannot remember doing). We are still working on one last testcase for the ENGINE branch, before we have it pulled into the Master, which will take about a week. Then a lot of the LB bugs should be fixed.

Kind Regards, Joost

Dear Markus,

I remember spotting something like this in one of the older versions of the master, but I tried to find it and could not reproduce the bug with the latest version, which one are you using?

KR, Joost

Yes, looks like something is at odds with the periodicity here. Can you
plot the z-velocity over x-position? That may point towards what is
going wrong.
