Required Modeling Entities
If you plan to mesh your model with AutoGEM before running an analysis or design study, you should follow a few common sense practices to ensure that all modeling entities are correctly accounted for in the mesh. In some cases, you must add the modeling entity before you mesh, while, in others, you can add the entity later. Here are the guidelines you should follow:
Entities you must add before using AutoGEM—You must add idealizations, connections, and simulation features that you want to use as a basis for another modeling entity—for example, a datum point that will be used to apply a measure—before running AutoGEM. Additionally, if your model includes point loads, constraints, or boundary conditions, you must add them as well. All of these modeling entities influence the mesh. If you do not add them before using AutoGEM, the mesh will not correctly account for these entities.
While it may not be absolutely necessary in all cases, we strongly recommend that you also define all properties before running AutoGEM. Defining properties before you run AutoGEM enables you to use the All with Properties option in the AutoGEM References area of the AutoGEM dialog box.
Entities you can add before or after using AutoGEM—Provided all reference simulation features and geometry are in place before you run AutoGEM, you can add loads, constraints, and boundary conditions before or after using AutoGEM. These entities must use curves, surfaces, or components as references; they should not use points. Also, you can add measures before or after you run AutoGEM. While Creo Simulate correctly accounts for modeling entities that you add to geometry after you run AutoGEM, it is a good practice to add all modeling entities prior to meshing the model.
