Dear Bernd,

Thanks for your reply.
When I try to Update the thermodynamic data as your suggestion, I meet the "Demixing in interface liquid\bcc-a2 component v" again. I used to solve this problem by using "mob_corr" without updating the themodynamic data. I remember that you suggested using the keyword "diagonal" in the "stoichiometric phases" section, but I can't input "diagonal" at this place(List of phases and components which are stoichiometric:).
In addition,when I start from a flat front without nucleation, I can't add a noise,only to change the smooth. Do I have to add a nucleation?

Dear Ling,

I was not aware that you use such an old MICRESS version :o

In the old version 6.2, you should use the keyword "interaction" without further parameters instead of "diagonal" to avoid the "demixing" problem.

Nevertheless, you can add noise using the keyword "noise" with a value for the noise level in [J/cm**3] in the driving force options for the corresponding phase interactions.

Bernd
