Possible bug when exporting .txt in DP_MICRESS

Hi MICRESS Team, I have been trying to export concentration data into text files from *.conc files (attached as *.conc1) and make some time-resolved concentration plots. However, when I tried to do that in DP_MICRESS, the program exits by itself after I click "export". There is a file generated but ...

Austenite Formation from Ferrite using MICRESS Examle

Hi all. I'm trying to simulate austenite formation from ferrite during intercritical annealing and I started by manipulating one of the MICRESS standard examples. I have a few confusion regarding how to edit the example drive file to reverse the transformation: (1) How are the phase assigned? i.e. i...

Re: Place randomly distributed nuclei

Hi Bernd, thanks for your suggestion! I increased the critical rex energy for the nuclei (to above the stored rex energy of the bulk grain) and the distribution is getting much more random. It is very helpful.
Danke schoen!

Re: Place randomly distributed nuclei

Hi Bernd, Thanks for your suggestions. I stick to the seed_undercooling model because I will introduce heterogeneous distribution of recrystallization energy later. I tried to vary the amplitude of random noise but nuclei distributions seem the same (see attached screenshot of the .korn files; left:...

Place randomly distributed nuclei

Hi all, this is my first post here... I'm doing a 2D benchmarking nucleation and grain growth simulation with MICRESS and I want to place randomly distributed grains into a bulk domain (i.e. no initial grain boundaries). The bulk domain is set to have a recrystallization energy of 3 MPa and the nucl...
