Hello Foamers


I am trying to solve a static bubble test as given in Albadawi et. al. My problem is my bubble is bursting when I refine my mesh. It work fine when there is 10 divisions per diameter but it burst if I do 20 divisions per diameter.



The link for Albadawi et. al. is given below:
https://www.sciencedirect.com/scienc...01932213000190


The drop radius=0.005m in a domain of 0.05x0.05.

Fluid density=1000 gas density=1
kinematic viscosity for fluid = 1e-3

kinematic viscosity for gas = 1e-5
Surface Tension between the fluids = 0.01


All in S.I unit



I am using the sclsVOFFoam solver developed by chalmers


http://www.tfd.chalmers.se/~hani/kur...ankarMenon.pdf


I tried with various boundary conditions zero gradient, fixed value, slip, cyclic none is working. Can someone suggest whats wrong am I doing!!

In the given test case of sclsVOFFoam why the setFields is between



p1 (0.25 0.5 -1) ;
p2 (0.75 0.5 1) ;


Shouldn't it be from



p1 (0.5 0.5 -1) ;
p2 (0.5 0.5 1) ;
