Analysis Challenge – 3D Reaction Pattern

Community,

The below snippet shows the solutions for 3D reactions that was calculated in Excel.   The spreadsheet follows the formulation of a NASTRAN RBE3 element.  RBE3 element theory and how it works can be seen in the attached PowerPoint on slides 17-23.  The numbers in white cells are given, and the numbers in gray cells are solutions.  The challenge is to reproduce the results in Excel.  Creo Simulate is extra.
