Diffusion Problem

[materialmoop]

Hi,

Thank you for your response I only have up to TCFe11 licensed, and I am using ThermoCalc2025a. I have now made the script more specific with regards to the phases:

set-echo
go dat
sw TCFe11
d-sys fe c mn si
l-sy CONSTITUENT
l-sy phases
rej phases *
rest phases liq fcc_a1 bcc_a2
get
app mobfe5
d-sys fe c mn si
l-sy CONSTITUENT
l-sy phases
rej phases *
rest phases fcc_a1 bcc_a2
get
go gibbs
save newFeCMnSi

However, when nucleation is supposed to begin, I receive the following error message many times: Thermo-Calc error 1611 MICRESS error 20 Thermo-Calc
Could you please tell me why I may be getting this error and how I could create the correct database?

Many thanks!

See here a list of the MICRESS error codes:

The undercooling cannot be calculated.

Your mobility database MOBFE5 might be incompatible to your thermo-dynamic database TCFE11.
Is this the newest mobility database you have?
There was a MOBFE6 published together with TCFE11 in 2021.

Best,
Ralph
