Example “galliumMelting2d” coupling FreeEnergy model

[Yupeng]

I plan to use the freeenergy model to simulate the interface in the galliumMelting2d case, but the calculation results will radiate around 32,000 steps, with energy and density equal to infinity. May I ask what the reason for this situation is?

[mathias]

The simulatio is unstable. There can be many reasons for it. Have you tried a finer resolution? You can stop the simulation shortly before it gets to infinity and output the results and check for the results in oder to find a possible source by looking at the location of high values.

Dear mathias,
Thanks for your reply,
The problem has been solved by changing dynamics and reducing relaxation time.
May I aks you an another question, which is about boundary condition.
I want to computing phase change process in 3D structure with a cylinder heating surface. The boundary condition of “setRegularizedTemperatureBoundary” in 2D should be changed to which kind of boundary condition in 3D.

Please, have a look at the other thermal examples..
