Bulk Temperature, Tb
If you do not import an externally computed bulk temperature, you must specify a bulk temperature for the software to use. Enter a real number for the bulk temperature of the convection condition you are defining.
Time-dependent bulk temperatures (and time-dependent heat loads) are only relevant for transient thermal analysis. For steady-state thermal analysis, be aware of the following:
Creo Simulate ignores time-dependent bulk temperatures.
If all bulk temperatures are time-dependent and there are no prescribed temperatures, a steady-state thermal analysis cannot run because the model has no valid constraints.
