Problem with T015_Gamma_Alpha_FeC_Acicular example
Posted: Tue Apr 28, 2020 9:57 am
Dear Bernd,
I am new to phase-field modelling and Micress software and I am already impressed with the capabilities of the method.
I want to simulate acicular ferrite formation to mimic the martensitic transformation. So, I started with the T015_Gamma_Alpha_FeC_Acicular example.
Everything is understandable so far but I am facing a strange problem. When I run the example, most of the times, the nuclei that are introduced in the microstructure do not grow and I get a final microstructure consisting of austenite with some ferritic nuclei being present (see figure). I rarely see the nuclei growing (Sometimes I think only one out of the three possible seed types can grow). In other words, I get different results by running the same script which is strange. Also, I have not changed anything in the script of the example.
I tried other examples that include nucleation, such as T010_Gamma_Alpha and it works fine.
In order to run the simulation, I import the file from the console mode of Micress software and I am using Micress 7.001.
What could cause this problem?
Best regards,
Stratos
