Working with Legacy Graphics

Prior to version 14.0, the contact algorithm in MotionSolve had a different criteria for mesh based contact simulation. As a result, it is possible that graphics in models having contacts might contain open surfaces, non-uniform mesh or just a surface(shell) mesh. To subject such graphics for mesh manipulation, the graphic h3d should be converted into a CAD or FE format so that the Import CAD or FE using HyperMesh utility can use it as an input file. Follow the below steps to translate the graphic h3d to an FE format using HyperView.
  1. Load the graphic h3d with defective mesh in HyperView as the model input. Turn off the result input option as shown. Click Apply.

    Figure 1.
  2. Go to File > Export > Solver Deck.

    Figure 2.
  3. In the Export Deformed Shape dialog, select Optistruct/Nastran from the Select format drop-down menu and provide a File name. Click OK.
  4. A confirmation dialog appears warning the user that this utility exports only unscaled-coordinates. Click Yes.

  5. In MotionView invoke the Import CAD or FE using HyperMesh utility and select OptiStruct as Input File format as shown below:

  6. Follow the rest of the process to access the Mesh Manipulation tool as described in the Mesh Manipulation Tool section.
