Thermo-Calc 2024b Update 1

The first release of Thermo-Calc 2024b was on June 19, 2024.

To learn about all the original software and database news see our release overview blog post or read the 2024b release notes.

Material Specific Property Model Library Bug Fix

This update is specifically for anyone using the following Property Models that are contained in these Model Libraries and also require additional database licenses:

  • Steel Model Library
  • Nickel Model Library
  • Titanium Model Library

The update fixes a bug related to a TC-Python license issue and the new Parallel calculation checkbox that significantly improves calculation time for Property Models.

Updating your software will fix the problem where all the material specific Property Models cannot be run without an active TC-Python licence if the new Parallel calculation checkbox is also selected, which is the default.
