- Basic Small Displacement Finite Element Analysis
  - OS-T: 1000 Linear Static Analysis of a Plate with a Hole
    This tutorial demonstrates the creation of finite elements on a given CAD geometry of a plate with a hole. Further, application of boundary conditions and a finite element analysis of the problem are explained. Post-processing tools are used in HyperView to determine deformation and stress characteristics of the loaded plate.
  - OS-T: 1010 Thermal Stress Analysis of a Coffee Pot Lid
    In this tutorial, an existing finite element model of a plastic coffee pot lid demonstrates how to apply constraints and perform an OptiStruct finite element analysis. HyperView post-processing tools are used to determine deformation and stress characteristics of the lid.
  - OS-T: 1020 Normal Modes Analysis of a Splash Shield
    In this tutorial, an existing finite element model of an automotive splash shield is used to demonstrate how to set up and perform a normal modes analysis. HyperView post-processing tools are used to determine mode shapes of the model.
  - OS-T: 1030 3D Inertia Relief Analysis
    An existing finite element model is used in this tutorial to demonstrate how HyperMesh may be used to set-up an inertia relief analysis. The analysis is then performed using OptiStruct and post-processed in HyperView.
