Before You Run an Analysis or Design Study
Be aware of the following before starting your run:
You may want to check your Creo Simulate settings to determine how the software processes your model during analyses and design studies.
You can use Creo Simulate settings to determine the following:
whether Creo Simulate includes datum curves or surfaces in the mesh
the defining ranges that Creo Simulate observes when creating elements
whether Creo Simulate treats the model as a shell or solid
You can check your model for errors before you start a run by clicking Info > Check Model on the Analyses and Design Studies dialog box.
If you select an invalid design study to run, Creo Simulate displays an error message after you select Start or Batch. Examples of invalid design studies include:
a design study containing an analysis that requires measures for convergence but has no measures selected
a sensitivity or optimization design study with no parameters
Creo Simulate deletes a standard or sensitivity design study if you delete the only analysis belonging to that study.
You should run only one design study at a time to avoid using too much memory.
