Not really. Physically, the solid-liquid interface has a finite thickness so any given level set is not representative. Often arbitrary limits are set to measure the depth of the interface, perhaps 0.1 and 0.9 though I don't know off hand of the physical arguments for setting these limits. > What is the phase field value phi in the interface thickness? Not sure what you mean. If you are asking "What's the value of the phase field is in the diffuse interface?", then the answer is that the value is anything between 0 or 1, or between any arbitrary cut off values one wishes to define. Hope this helps. Cheers. -- Daniel Wheeler
