  1. All thermal properties are automatically scaled by Time-factor. The thermal behavior (or effect) corresponds to computation time multiplied by Time-factor.
    With the following imposed flux in the input deck:

    #---1----|----2----|----3----|----4----|----5----|----6----|----7----|----8----|----9----|---10----|
    And in the Engine file:
    /RUN/TEST/1
    0.2
    /THERMAL
    1000

    The thermal flux starts at run time = 0.05 s (50/1000) and stops 0.3 s (300/1000).

    The thermal flux received in the element from time 0.05 to 0.2 s is equivalent to the same model without /THERMAL computed up to 200 s.

  2. The thermal parameters defined in the input deck should be the physical ones.
  3. This thermal factor control works for thermal analysis with solid, shell, and sph elements for the following entities:
