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 |
|---|
| 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.
|
| 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 to display the dialog.
|
| The breakage calculation is only for long fiber materials (initial length >1mm). For short fiber materials, the solver turns off the breakage calculation, automatically. 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. |
| Opens the Fiber breakage parameters dialog to edit options relating to the prediction of fiber breakage. |
| 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. |
| Specifies whether the anisotropic effect of fiber orientation on the thermal conductivity is considered in the analysis. The default setting is No. Note: This option is available for 3D mesh type only. |
| Specifies whether the anisotropic effect of fiber orientation on the polymer rheology is considered in the analysis. The default setting is No. When the setting of Yes is selected, the normal (isotropic) viscosity is not representative of the flow resistance and so that result will not be included in the analysis results. Note: This option is available for 3D mesh type only. |
