divergence behaviour of interFoam solver for very fine mesh
 
1 Attachment(s)
Dear Foamer,

I am trying to simulate two phase flow through a nozzle with contraction ratio equal to 10. It is flow of some liquid like water, glycerine etc. into air medium. I am using interFoam solver to simulate this problem.

It works fine for relatively coarse mesh but starts to diverge at very fine mesh and divergence starts at liquid-air interface.

In the picture below You will see one fourth of geometry and expected velocity is about 30 m/s.
