Hello.
In the modeling of recrystallization using phase field model, some authors chose a value such as 1e9 for nucleation density. But there is not reason for selecting this kind of value or it is not clearly explained why this value!.
I'd like to know the basis of defining this physical parameter.
Thanks

We select the nucleation density based on comparison between experimental data and simulation results. Actually, nucleation density is fitting parameter.
You can not use other paper's value if your mesh number and size are different.
hello!
I saw your question on What is the effect of initial nulcleation density in the phase field model and thought of contacting you. Good to know you are interested in this field! Judging from your question, are you similar to the research work of Professor Takaki? I happen to study in accordance with his thinking now, and I also find that there are many questions and I don't know how to solve them?
For example, how to control the nucleation rate when the initial nucleation of recrystallized grains is set? I am now facing the situation where the recrystallized nuclei do not grow up
Good luck! Li
