Vasileios Angelidakis proposed the following answer:
Hi Jie,

Depends on what stage of your analysis you are.

If you just want to stabilise your sample/particle during
initialisation, you can use local damping (in the NewtonIntegrator),
which is un-physical but will do the job.

If you want to keep some damping during the main stage of your main
simulation, I would advise to not use local damping, but use a small
amount of viscousDamping in the KnKsPBLaw instead.

If now you want to stabilise your system during initialisation
momentarily, you can invoke "calm()" for some timesteps, to reset the
velocity of the particles.

Hope this helps,
Vasileios
