What is “Property Change Limit”?

      While solving transient thermal I notice the parameter called "Property Change Limit = 0.05". What exactly is this parameter?

      I understand that the temperature (and other properties) are calcualted by performing a matrix inversion after assuming/calculating a time-step value. How does this parameter come into play here?

      The only info on this found is in the help manual under the THOPT command in the command reference section (this command is sent to the apdl solver in the ds.dat file that is created by workbench - THOPT specifies nonlinear transient thermal solution options – QUASI method).

      Hope this helps
