Welcome to the ELFINI Solver Verification Guide. This guide provides a series of mechanical problems to test the accuracy of the ELFINI Finite Element Solver.

This overview provides the following information:


Before Reading this Guide

Before reading this guide, we recommend you to read the:

  • Generative Structural Analysis User's Guide

  • Advanced Meshing Tools User's Guide

  • Finite Element Reference Guide.

You may also like to read the following product guides, for which the appropriate licenses are required:

  • Infrastructure User's Guide Version 5
  • Part Design User's Guide
  • Assembly Design User's Guide.

Getting the Most Out of this Guide

To get the most out of this guide, a table presents you the analytical or reference solution, and compares it with the computed results in CATIA. To check these results, you can also perform the test, using the associated CATPart or CATAnalysis document, and following the procedure.

First, we indicate the licenses you need to play the tests:

The tests are divided in the following distinctive chapters:

  • Static Analysis: description of several linear static analysis problems and comparison of results.
  • Modal Analysis: free vibration analysis of several problems and comparison of results.
  • Buckling Analysis: computation of critical loads creating structure instability and comparison of results.
  • Dynamic Response Analysis: dynamic analysis of several problems and comparison of results.
  • Thermo Mechanical Analysis: thermal expansion of an element and comparison of results.
  • Analysis Assembly: analysis of several elements assembled with a fastened connection and comparison of results.
  • Composites: analysis of composites created with isotropic and orthotropic materials and comparison of results.

Accessing sample documents

To perform the scenarios, you will be using sample documents contained in the online/elfug/samples folder.
For more information about this, please refer to Accessing Sample Documents in the Infrastructure User's Guide.
