Mapping pressure or temperature results to a mold mesh surface for export to ANSYS for mold deflection analysis

To map pressure or temperature time series results to a mold mesh surface for analysis with ANSYS software, you must have separate 3D meshed models of the part and the mold, stored in separate study (*.sdy) files in the same project.

• The mold mesh property should be defined as either Part insert (3D) or Core (3D).
• The specified Mold material property must be the same on both the part model and the mold model.
• The part model and mold model geometries must mate to each other, but the nodes and elements on the mating surfaces do not have to coincide.
• The mold mesh must have enough nodal constraints applied for stress analysis.

This feature is available only for 3D models when an analysis sequence that includes Fill+Pack is selected.

Note: This feature is not supported for the Underfill Encapsulation molding process.

1. Ensure that you have 3D meshed models of the part and the mold saved in separate studies in the current project; for example, part.sdy and mold.sdy. Typically, these models are prepared for a core deflection analysis, and the mating surfaces must match.
2. Ensure that the mold properties specified for the mold mesh are identical to the properties that are defined for the mold steel in the part mesh.
3. Open the part study (for example, part.sdy) and select an analysis sequence that includes Fill+Pack.
4. Click (Home tab > Molding Process Setup panel > Process Settings) to open the Process Settings Wizard.
   1. If necessary, click Next until the page on which the Advanced options button appears is displayed.

      For thermoplastics molding processes, this is the Fill+Pack Settings page. For thermoset molding processes, this is the Profile Settings page.

   2. Click Advanced options.
   3. In the Solver parameters group, click Edit.
   4. Click the Interface tab, and click ANSYS options.
5. In the ANSYS Options dialog, set the Separate finite element mesh for mold option to Specify it, and click Specify filename.
   1. In the Mold mesh model filename text box, type the name of the study in the current project that contains the mold mesh model, for example, mold.sdy.
   2. From the Select part data to pass onto mold mesh list, select the results you want to map onto the mold mesh: Pressure history, Temperature history, or Both pressure and temperature.
   3. From the Solution method list, select the type of analysis to perform in ANSYS: One step steady or Multi-step transient.
6. Click OK four times to return to the Process Settings Wizard.
7. Specify any remaining process settings, if necessary click Next until the last page appears, and click Finish to close the Process Settings Wizard.
8. Click (Home tab > Analysis panel > Start Analysis).

When the analysis is complete, run the mpi2ans.vbs macro to generate the interface files for input to ANSYS. See Exporting model and results to ANSYS for details about generating the interface files.
