3D residual stress model as default for the 3D warpage

The 3D residual stress model was an option in 2017 R2. With the 2017.3 release, this model is now the default.

You can now get more accurate results for the shrinkage, warpage, and molded-in residual stress, without having to change the 3D shrinkage model. If you leave the default settings, the Uncorrected residual stress model is run, by default.

Basic workflow to change back to the Generic shrinkage model:

Note: Make sure you have a 3D model, and that you select an analysis sequence that includes Warp.

1. Click (Home tab > Molding Process Setup > Process Settings).
2. If necessary, click Next until you reach the page with the Advanced options button.
3. Click Advanced options.
4. Click Edit associated with the Molding material.
5. In the Thermoplastics material dialog, select the Shrinkage Properties tab, then select the Generic shrinkage model model from the Select a shrinkage model (3D) drop-down list.
