Nucleation model in MICRESS

Dear all, I am trying to understand the nucleation model implemented in MICRESS. I found a very old thread https://board.micress.de/viewtopic.php?f=10&t=10 discussing about it. In this thread, it was mentioned that In general, these models are designed for simulation at microscale, not at nano-scale...

Adaptive Interpolation in TQ interface

Dear MICRESS team, I came across this publication: "Larsson, H., & Höglund, L. (2015). A scheme for more efficient usage of CALPHAD data in simulations. Calphad, 50, 1-5." In this work, they propose an interpolation scheme which can speed-up the data retrieval from CALPHAD and it was mentioned that ...

Re: Averaging the driving force across the interface

Thank you Brend. One more question, for solid-solid transformation, is this averaging still necessary ? We don't expect solute trapping in solid-phase transformations right ?

Averaging the driving force across the interface

Dear all, There was a discussion about driving force averaging in the MICRESS manual. <<< ------- From Manual (Vol 2, Section 3.2.1)----- >>> 3.2.1 Driving force options The driving force options in the phase-interaction input allow increasing numerical stability and (together with the interface mob...

Re: paraequilibrium simulation

Thank you very much Deepu and Brend. I dont why I am not getting notifications for new posts. I have turned on the notifications from the user profile. Deepu: As you have correctly predicted, I can't do ATC in my version of MICRESS :( . But I found your reference very helpful. Brend: Actually, v5.4 ...

Re: paraequilibrium simulation

Hi Brend, I have been looking in the forum to understand the different redistribution models used in MICRESS, epecially "para" and "nple". I presume "nple" will not allow for any partitioning but what does "para" do ? I tried looking up on "Paraequilibrium" but no use. And it is not described in the...

Re: input of static anisotropy changed!

Hi Brend, I didn't know whether this question is appropriate in this topic or the topic on Gibbs-Thompson effect. I want to be able to calculate the Gibbs-Thompson coefficient from input the surface energy in the driving file. From the MICRESS Manual (Vol.0 - Page 8 ; Version 6.3), I found the follo...

Re: Error in reading diffusivity from database

Thank you very much, Brend. I plan to use these data. But in the manual entry, I need only "Diff.Coeff" and "Activation energy" . What is meant by "Frequency term". I tried looking it up in the manual(v6.3) but could not find it. For example, for the LIQUID phase: I understand the numbers 5.183E-05 ...

Re: Error in reading diffusivity from database

Dear Ralph and Deepu, Thank you very much for your quick responses. I greatly appreciate that. Deepu: Probably you are right. I am also planning to use manual diffusivity instead of getting diffusivity from the database. Interestingly the reading the information from the thermodynamic database (TCNI...
