Warp analysis

A Warp analysis is used to diagnose the cause of warping and recommend a solution, such as gate location changes, design parameter changes, or reduction of wall thickness variations.

Warp analysis is supported for Dual Domain and 3D analysis technologies.

Any attempt to predict the likelihood and amount of warpage for a particular component must first account for these shrinkage variations.

The material that is used influences the warpage of the part. Sometimes you must choose a material with low, uniform shrinkage to achieve dimensional accuracy. These materials are usually more expensive, but you may be able to use a cheaper material and save costs by observing shrinkage and warpage design principles.

Running a Warp analysis

To run a warp analysis, you must include a Fill+Pack analysis.

1. Open a model.
2. Click  (Home tab > Molding Process Setup panel > Analysis Wizard).
3. In the Sequence tab, select the Warp check box and then click Next.
4. If necessary, edit the Material properties and then click Next.
5. If necessary, edit the Process Settings properties and then click Next.
6. If necessary, edit the Packing Profile.
7. Click Finish to close and save the analysis entries, or Analyze to launch the analysis.

Once the analysis has finished, the Summary pane appears.

Note: Click  (Home tab > Analysis panel > Job Manager > Abort Job) to abort the analysis.
