How to Simulate a Model Using Finite Element Method

Step-by-Step Guide

1. 1

   Step 1: In order to simulate a model

   Follow the blueprint provided (Unit in Inches). ,,,,, Select the second NX Nastran (Type Sim), click Ok on all popup windows.,,,, Refer to the tips section for location of WCS., The computer will now solve for the parameters, give it a few seconds.,,,,, Congratulations, you have performed your first Finite Element Simulation.
   
   Take a look at the video below for what its supposed to look like when animated.
