Exporting

Select the export options and write out the files used in the FEA simulation.

Export Settings

1. Click (Home > Export > Settings).
2. Select from the list of options available on the General tab:
   • Output Warpage (only available if a Warp analysis was performed in Moldflow)
   • Output Weld Surfaces (only available if weld surface strength analysis was activated in Moldflow, activated by default if weld surfaces are present)
3. Select from the list of options available on the Rupture tab:
   • Enable Rupture (only available if Elastic-Plastic material model is selected, deactivated by default)
4. Click OK.

Output Warpage

If the Output Warpage check box is activated, the warpage data from Moldflow will be stored in the .sif file. Additionally, a HIN file is created that contains the keyword *CURE STRESS. This keyword will tell the solver to include the effects of thermal residual stresses and strains in the structural analysis. Refer to the Model Thermal Residual Stresses section for further details.

Output Weld Surfaces

To activate or deactivate the Output Weld Surfaces check box, a body with weld surface results must be active in the display window. If the Output Weld Surfaces check box is activated, all weld surface results are stored in the .sif file.

Enable Rupture

If the Enable Rupture check box is activated, matrix rupture is evaluated at every integration point in the model. When rupture occurs, the stiffness of the material at that integration point is instantaneously reduced to a fraction of its pristine value. The stiffness degradation allows the load to be redistributed to surrounding integration points. Ultimately, enabling rupture allows the prediction of damage evolution. Be aware, activating this option will result in increased run times. Refer to The Rupture Model topic in the Theory Manual for more information about the criterion used to determine when rupture occurs and the consequences of the satisfied rupture criterion.

Export

1. Click (Home > Export > Export to Structural Package).
2. After the Export File to Structural Solver dialog appears, navigate to the directory where the files should be exported, and give the file a name.
3. Click Save to begin the export.

After the is complete, you will see an input file (.inp, .cdb, .dat, .bdf, or .nas) and an interface file (.sif) in the directory you selected. The input file contains the part geometry, mesh, load and boundary conditions, and the user material definition. The interface file contains the mapped fiber orientations, the residual strains, and the weld surface information.
