To set up a wall slip analysis, either follow the order of the buttons on the Home tab of the ribbon UI, or follow the order of the items in the Study Tasks pane. Make sure you have a 3D model, and that you select an analysis sequence that includes Fill.
Note: There are some recommendations for you to consider when setting up a wall slip analysis, to ensure you maximize the effect:
- Mesh your model with 16-18 layers through the thickness, instead of the default 12 layers.
- Increase the surface mesh density, particularly where you expect to see jetting.
When you get to the process settings, to enable a wall slip analysis:
- In the Process Settings Wizard dialog, click Next if necessary until you find the Advanced options button.
- Click Advanced options.
- Click Edit associated with the Solver parameters.
- In the Fill + Pack Analysis tab, ensure that Simulate wall slip is set to Yes, then click Edit wall slip parameters and enter your material data.
- Check the Simulate inertia effect option to enhance jetting.
- Click Filling parameters, and change the Maximum %volume to fill per time step to 1% instead of using the default 4%.
When all the items in the Study Tasks pane have check marks against them, the analysis is ready to launch.
