hi all,

i was trying to setup a simple case of rise of air bubble in glycerine, but solution continuity starts diverging as soon as i start iteration.

my setup is:
mesh: cylinder rad:0.006 , height: 0.6

vof,no. of phases 2, courant no. 0.25,implicit body force,
unsteady,1st order imp.
adapted region : sphere radius .005
body force weighted, simple

i have tried simplifying mesh and everything but nothing works.
