Autodesk Nastran In-CAD Essentials

Nastran In-CAD is a general-purpose finite element analysis (FEA) tool that allows a wide variety of simulation types to be performed directly inside Autodesk Inventor. This course provides an ideal introduction to the software, as it contains examples of many different analyses, provides an overview of FEA concepts and setup, and covers common process for troubleshooting errors during solving. This course is an ideal prerequisite to a more focused workshop covering specific or more advanced analysis requirements.

The course covers the following type of analysis:

  • Linear static
  • Non-linear static
  • Thermal
  • Buckling
  • Modal analysis
  • Modal frequency response
  • Dynamic fatigue
  • Non-linear transient analysis (impact)


Prerequisites

This course assumes familiarity with Windows operating systems, and some knowledge with Autodesk Inventor modelling, as Nastran In-CAD is accessed directly inside Inventor.
Any previous experience with finite element analysis, such as Inventor Professional FEA, Ansys, etc. is advantageous, but not essential.
