- 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:

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