NAFEMS Benchmark Problems and FEA Interfacing Bonus Assignments Overview

This document outlines the requirements for two bonus assignments for the NAFEMS Benchmark Problems. The first assignment involves solving three benchmark problems using hierarchical mathematical models with a focus on 2D plane stress, 3D shell, and 3D solid studies. Students are to select their preferred mesh and solve two studies. The second assignment focuses on motion and finite element analysis (FEA) interfacing, requiring kinetic analysis and the export of load results. Both assignments have a deadline of April 11th, 5:00 PM.
