Re: Phase Diagram Input for Multi-component Systems with NPLE

Hi Bernd, thank you very much for your reply. With mob_corr my kinetics make more sense. Now under NPLE for Mn and "normal mob_corr" for C, I am able to replicate my DICTRA result (see the plot attached; red curve is the MICRESS result) even after the NPLE-PLE transition. NPLE_PLE_transition_1075_ov...

Re: Phase Diagram Input for Multi-component Systems with NPLE

Hi Bernd, I have some further questions on a similar system, although not on phase diagrams. I am running (once again) 1D α-to-γ tests on Fe-C-Mn ternary systems with TQ coupling. Under diffusion control, kinetics is usually fast at the beginning (C-diffusion controlled and close to NPLE), reaching ...

TQ initialization failed

Hi all, I have tried to start on the TQ coupling function of MICRESS (v6.402 on a linux-based computing cluster) and I started with the AlCu example. I obtained a GES5 file from ThermoCalc 2019a. However, an error message occurred saying "TQ initialization failed!" without more specific explanations...

Re: Artefact of Phase Content and Concentration Profile in a 1D Simulation

Hi Bernd,
Thanks for your suggestions! After some tweaking I found that changing the composition in phase 2 is the most effective way to avoid this artefact. Apparently I forgot some basic principles and used unreasonable numbers in my previous simulations.

Re: Artefact of Phase Content and Concentration Profile in a 1D Simulation

Here in another simulation of mine where I also included Mn (component 2), a similar artifact occurred. This time however, the interface appears to be very thick and I cannot see the austenite slab in the middle.

Artefact of Phase Content and Concentration Profile in a 1D Simulation

Hi all, I have encountered a possible artefact. I am trying to simulate austenite formation from ferrite with a simple 1D, isothermal model (input files attached). Initially both the parent ferrite (phase 1) and austenite have a nominal C concentration of 0.039 wt%. When I start a simulation at 1100...

Unable to run DP_MICRESS on Linux

Hi all, I have recently changed to Linux but I cannot seem to run DP_MICRESS using the .tgz file downloaded from the main website. I tried to run it in terminal but it tells me something is wrong about shared libraries. I Use OpenSUSE Tumbleweed; one of my colleagues running Ubuntu cannot run DP_MIC...

Re: Possible bug when exporting .txt in DP_MICRESS

Hi Ralph, I had a try a few minutes ago and it is fixed in the latest version.

Thank you very much!

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...
