Stress relaxation time history requires more than one point.
Heat treatment schedule card *STRF requires time values to be non-negative. Input a valid heat treatment schedule.
Heat treatment schedule card *STRF requires the heat treatment history to be specified. Input a valid heat treatment schedule.
Heat treatment schedule set by *STRF card requires the time values to be entered in ascending order.
These errors occur when the time history specified by *STRF is invalid. Heat treatment schedules must have at least 2 time-temperature sets that increase in time ascending order. Correct the heat treatment schedule and resubmit the simulation.
Stress relaxation *STRF can only be used when part-level plasticity *PPLA is on. *STRF card will be ignored.
Stress relaxation *STRR can only be used when part-level plasticity *PPLA is on. *STRR card will be ignored.
These errors indicate that the user attempted to enter in a heat treatment relaxation temperature or temperature history without enabling part-level plasticity, using *PPLA. Add the *PPLA card to the mechanical input file and rerun the simulation.
Stress relaxation temperature is specified without the heat-treatment time-history.
Stress relaxation temperature is not specified for heat treatment.
These errors occur when the heat treatment history *STRF has been used without a heat treatment stress relaxation temperature *STRR, or *STRR without *STRF. Make sure the heat treatment history has been added to both the thermal and mechanical input files and that *STRR has been included for each of the material properties specified.
