HyperSizer NASTRAN Interface - Advanced Ringframe Modeling
« on: September 11, 2008, 04:06:15 PM »
A new training Powerpoint presentation has been uploaded to the HyperSizer Downloads.

The scope of the presentation:

  • Semi-Advanced Topic: Meant for “final” sizing for a custom manufactured frame configuration rather than preliminary design.  In preliminary design, we recommend single row of CBARs with HyperSizer built-in beam concept
  • Two modeling approaches are presented:

    • Option A: Preliminary Sizing: Less detail and accuracy is captured by using fewer elements while the overall sizing is more flexible
    • Option B, Final Sizing: More detail and accuracy of the ringframe is captured using more elements, but less flexibility in the overall sizing

  • Some topics covered here are related to FEM modeling of a specialty, custom ringframe and are not specific to HyperSizer
  • Complexity of specifying beam orientation, grid ordering, normals, etc. are not specific to HyperSizer.  These issues would need to be addressed for any analysis involving FEA.
  • See detailed discussion for beam orientation in the HyperSizer Pro User’s Manual
