Fiber Solver Parameters dialog

Use this dialog to specify the settings for the solver parameters related to Fiber orientation prediction in a Fill or Fill+Pack analysis sequence.

To access this dialog, ensure that you have selected an analysis sequence that includes Fill+Pack , click (Home tab > Molding Process Setup panel > Process Settings), if necessary click Next one or more times to navigate to the page with the fiber orientation option. Select the option Fiber orientation analysis if fiber material, then click Fiber Solver Parameters.

Note: All solver parameters have a default value that will be suitable for most analyses.

Note: If the shrinkage model for the selected material is set to CRIMS, and the Use CRIMS option on the CRIMS Shrinkage Model Coefficients dialog is set to the default ( change solver parameters to be consistent with the CRIMS model ), any changes that you make to the solver parameters above will be overwritten in the analysis. If you want to use non-default settings for these solver parameters, either change the Use CRIMS option setting, or select a different shrinkage model.

General settings

Dialog element	Explanation
Apply fiber inlet condition at	Specifies whether the fiber orientation calculation begins at the part gate or at the injection location. Gate This is the default setting. The fiber orientation calculation begins at the gate (entrance to the cavity), even if the model includes a runner system. Injection location If you select this option, the fiber orientation calculation begins at the injection location. This accounts for the fiber orientation in a runner system, if one exists in the model.
Fiber inlet condition	Specifies the inlet boundary condition of the fiber orientation state. Fibers aligned at skin / random at core This is the default setting. Fibers aligned at skin / transverse at core User-supplied inlet orientation Select this option if you want to specify the in-plane fiber orientation components through the thickness. Click Edit profile to display the User-supplied inlet orientation dialog.
Calculate fiber breakage	Specifies whether to include fiber breakage calculation in the fiber orientation analysis, if the selected material is a long fiber-filled material. Note: The default setting is Determined by length. If you don't want to include the fiber breakage calculation in your analysis, select No from the drop-down menu.
Fiber breakage parameters	Opens the Fiber breakage parameters dialog to edit options relating to the prediction of fiber breakage.
Composite property calculation options	Opens the Composite property calculation options dialog to edit options relating to the prediction of the mechanical properties of the composite, that is, fibers plus polymer matrix.
