JMatPro® version 12.4 released

Version 12.4 (January 2021)

  • fixed missing temperature line in QForm export file

Version 12.3 (December 2020)
*UPDATES FROM VERSION 12.2 to 12.3 are only necessary for Cu alloy users*

  • fixed calculations for Cu alloys failing (introduced in 12.2)
Version 12.2 (November 2020)

  • in steel solidification/quench properties graphs, added a note about whether secondary


    were included or not
  • steel TTA calculation: homogenisation temperature calculated when relevant

  • export to COMSOL Multiphysics for steel heat treatment

  • fixed quench properties/welding cycle/advanced TTT calculations failing when running with K or F as temperature unit
  • fixed choice of old/new format in Sysweld export

  • fixed a bug in cooling curve calculations which can lead to erroneous results if a minor phase appears before a major one
  • fixed possible failing calculations in Advanced TTT when the chosen temperature unit was K or F
Version 12.1

  • corrected a bug preventing calculations of "Quench Properties" being made for multiple cooling rates when secondary phases were included
  • fixed double inclusion of Scandium in the list of elements for Al alloys. This created problems of saving the right composition
Important: this fix for Sc means that files with the wrong compositions may have been saved if you have used version 12.0 for Al alloys including Sc 
To correct this:
a) Install version 12.1 or above
b) When JMatPro® starts, look into the DOS shell and it will say JMatPro® will run in xxx. This will give you the base folder where files are stored. Close JMatPro® and in this base folder, find the inits/elts.ini file. Delete this file
c) In "File->Load Material File" delete all mat files created in version 12.0 for which there is Sc in the alloy composition
d) In "File->Load Composition" delete all compositions saved in version 12.0 for alloys which should contain Sc
