No, you should not use the gradient condition for concentration in this case!

Re: Interfacing Micress with Matlab
Dear Raghav, Principially, this should be possible with Matlab, because only the temperature curve input has to be modified, which can be read from an ASCII file, and the results have to be taken from the .TabK or .TabGD file which are also ASCII files. But, as I already said, I personally have no e...

Re: Interfacing Micress with Matlab
Hi Raghav,
I'm sorry, but I have never done something like that!
Which type of data do you want to pass between MICRESS and Matlab?

Re: Initial Microstructure
This is correct! If you don't want to live with the additional interfaces, gradient should be used because isolating boundary conditions as well as symmetric always lead to interfaces which are perpendicular to the border of the domain, which is bad for grain growth. But be carefull and use the grad...

Re: Initial Microstructure
Dear zhubq, Of course, using periodic boundary conditions with experimental microstructures is a fundamental problem, because experimental structures are never periodic. In the Grain-Growth examples on the MICRESS distribution CD, it can be seen what happens in that case: an extra grain boundary is ...

Re: KTH Solute Drag
Dear ning, The .driv output displays only the chemical part of the driving force. This may exist for interactions between different phases or for recrystallisation, but it does not include curvature contributions. Thus it depends on the example whether the .driv output will show anything or not. The...

Re: KTH Solute Drag
Dear ning, the sd_kth option in the mobility input is a special solution for KTH in Stockholm which makes no sense for other users ( see also here ). You can use instead a constant, temperature dependent or driving force dependent mobility. In the latter two cases, the input format is an ASCII file ...

Re: nucleation issues
Dear zhubq, I'm sorry for not answering before, I am on holidays and had no internet connection! If you use stabilisation, it does not matter whether you input a radius of zero or any other value smaller than the grid spacing. In all those cases, a "small" grain with a fraction of 2.01 x phMin will ...

Re: averaging driving force and analytical curvature
Dear ning, Welcome to the MICRESS forum! I will try to give you an answer to your questions or the links to threads in this forum where these topics have already been addressed. Please don't hesitate to ask again if not everything is cleared up! 1.) In the dimension parameters, enabling averaging in...

Input changed
Hi all! In the input of the recrystallisation energy, there has been a slight change. Now, also in the nucleation input, specification of the recrystallisation energy is possible/necessary! The reason for this modification is, that one can not always assume that the deformed structure with recrystal...
