The 3D Warp advanced options dialog allows you to specify analysis options for a 3D Warp analysis if you have not chosen to enable mesh aggregation.
To access this dialog, deselect the Use mesh aggregation and 2nd-order tetrahedral elements check box in the Warp Settings page of Process Settings Wizard, and click the Advanced options button.
3D Warp advanced options
- Warpage analysis type
- Allows you to select the type of Warp analysis to run.
- Small deflection warpage analysis
- This type of analysis allows you to enable the
Isolate cause of warpage
option if you want the small deflection that you are setting up to output information about the dominant cause of warpage.
- Large deflection warpage analysis
- Select this analysis and, optionally, specify the settings for the solver parameters to run a large deflection Warp analysis.
- Upgrade tetrahedral elements to second order
- Specify whether the 4-noded tetrahedral elements (first-order elements) created by the mesher should be upgraded to 10-noded tetrahedral elements (second-order elements) in the 3D Warp analysis.
In thin-walled areas of the part, second-order elements will improve the accuracy of the prediction.
The following options are available:
- Automatic
- Select this option if you want the warpage solver to automatically upgrade elements in thin-walled areas of the part to second order to improve the accuracy of the results. For many typical injection-molded parts that are thinner than their length or width, this option will be equivalent to upgrading all elements to second-order.
- None
- Select this option if the part contains thin-walled areas but you do not want second-order elements to be used either a) because you want the analysis to run as fast as possible regardless of the loss in accuracy incurred, or b) a previously attempted analysis using the Automatic setting, on a very large model, failed due to insufficient system resources.
- All
- Select this option if you want the warpage solver to upgrade all elements in the part to second order for most accurate results. This setting will however result in the longest analysis time.
