Tasks to set up a Fiber Orientation analysis

Use the process settings to enable a fiber orientation analysis.

The setup tasks below are for fiber-filled thermoplastic materials.

Note: There are some recommendations for you to consider when setting up a fiber orientation analysis:
  • To obtain fiber length results, ensure you have selected a long-fiber composite material, and the option to Calculate fiber breakage is set to Determined by length.
  • To obtain a fiber length weighted distribution result, activate the option to Output fiber length weighted distribution and select the nodes you want included.
  • For most other results, ensure that you have selected a shrinkage model in the process settings.

When all the items in the Study Tasks pane have check marks against them, the analysis is ready to launch.
