Guidelines for MEC/T Temperature Loads
For MEC/T temperature loads, keep the following guidelines in mind:
• You must have defined at least one steady-state thermal or transient thermal analysis to define a MEC/T temperature load.
• If you are importing a thermal load from a transient thermal analysis, the transient thermal analysis must have at least one output step with
Temp load selected. Use the
Output tab of the
Transient Thermal Analysis Definition dialog box to make this selection.
Similarly if you define the MEC/T load based on a steady thermal analysis with load histories you need to define at least one output step on the Steady Thermal Analysis Definition dialog box and select the Temp load check box.
• A MEC/T temperature load allows you to use the temperatures from a previously-defined thermal analysis as a thermal load in a structural analysis. You can run the thermal analysis in the same
design study as the structural analysis or you can run the thermal analysis before you run the structural analysis. However, if you choose the latter approach and you have defined dimension parameters for your model, the parameter settings you use in the Structure design study must match those of the Thermal study.
• You need to supply a reference temperature for MEC/T temperature loads. Creo Simulate calculates the temperature change at a given model location as the difference between that location's temperature as determined in the thermal analysis and the reference temperature.
• The mesh must be identical for the thermal and structural models. Thermal ignores springs and masses.
