An error in Abaqus AM modeller

[AutoAA]

Hi, I am having an issue with the modeling of the additive manufacturing simulation for Ti-64_Al. The problem is the convergence of heat flux equilibrium. You are requested to share any suggestion about this problem. you can find ".msg, and .inp" in the attached files.

HEAT FLUX EQUILIBRIUM NOT ACHIEVED WITHIN TOLERANCE.
NOTE: THE RATE OF CONVERGENCE IS VERY SLOW. CONVERGENCE IS JUDGED UNLIKELY.

More input (not .inp, other extensions) files are needed to run this analysis. At least heat_path.txt is needed here but make sure that there are no other missing files.

Hello FEA way,

Thank you for your reply. You can find the heat path and material path int the attached file.

Thanks!

This model is from Abaqus 2018, released long before AM process simulation functionalities were implemented, removing the need to download and install the AM Modeler plug-in and use some additional files with subroutines. Also, many bugs have been fixed and several new functionalities added since 2018. Is it possible for you to upgrade to Abaqus 2022 or, even better, 2023 ?

Dear FEA way,

Thanks for your reply. For now, I will not be able to upgrade to ABAQUS 2022 or 23.

Thanks

But, many be you can try the attached file. It is written in .py so that we don't have to concern about the version of ABAQUS.
