Hello all,
I am trying to study a very simple case of bubble rise ( air in water) using Phase field method in COMSOL. However, again and again I get this error " fFailed to find consistent initial values.
Last time step is not converged."
I see that there is some scaling setting that needs to be done. However, just to see of things work well, I took the exact parameters as given in example of capillary filling.
The only difference in my case is that I try to study the rise of bubble instead of capillary filling.
While the given example worked well, changing the boundary conditions and physics lead to an error mentioned above.
May some one help in this regard, please? How to deal with this issue. I looked across but not much was found.
Thanks
You may need to set a reference pressure point at any point of the bottom surface.
