Simulations with a small outflow object - Marvin

In my previous post I have shown that the inner rim of the CND is stable when a resolution level of 4 is used (0.04 pc). I show here a similar simulation, but now with a central outflow object. The following animaion shows the surface density of the disk, the small black circle marks the outflow object, the large black circle the initial inner rim of the accretion disk. Surprisingly the disk's inner rim moves inwards until it hits the outflow object. Maybe the large velocity gradients/fluctuations increase the numerical viscosity in these simulations?
