Model Imperfection for Large Deflection Analysis dialog

This dialog is used to specify a model imperfection to be applied to the model to assist the convergence of a large deflection analysis.

To access this dialog, ensure that you have selected an analysis sequence that includes Warp or Stress. Click (Home tab > Molding Process Setup panel > Process Settings), and if necessary click Next one or more times to navigate to the Warp Settings or Stress Settings page of the Wizard. Set the Warpage analysis type or Stress analysis type option to Large deflection , click Solver parameters, select the Apply imperfection to model to assist convergence option, and then click Edit settings.

Note: Only apply a tiny imperfection to the model, otherwise the change in geometry will affect the warpage prediction. The recommended scaling factor to use is one of the following:

• 1/1000 of the part length expressed in mm, or
• 1/10 of the part thickness expressed in mm.

Dialog element	Explanation
Create imperfection in model by applying	Specifies the source and magnitude of the imperfection to apply to the model, to assist the large deflection analysis in converging.
