Specify a Reference Temperature

Specify a reference temperature for the model prior to applying any load.

In contrast to traditional analyses using Simulation Composite Analysis, you must specify the temperature of the analysis in absolute temperature units (Kelvin or Rankine) as an initial condition.

1. Type the command TREF, 297.15.
2. This sets the initial reference temperature of the model, which is required for fatigue analyses, to 297.15.
