viscoplastic glass flow


I did find palabos few days ago. I am interesting in modeling viscoplastic glass forming.
Do you think that palabos can do that?

I did donwload palabos and run some examples, trying to understand.
ShowCase breakingDam is interesting.

I would like to try some test cases.
One is to see freesurface model. I have glass cube {it is hot glass so kynematic viscosity is cca 0.16} which I leave to spread on washer {bottom plate}.
I did modified breakingDam but I don;t know how to change boundary condition for bottom plate for slip.
I can paste the code here, can someone help with it? thanks
