analyses across statics and dynamics, vibrations, acoustics, fatigue, heat transfer, and multiphysics disciplines.
This tutorial demonstrates how to import an existing FE model, apply boundary conditions, and perform a modal frequency
response analysis on a flat plate.
In this tutorial, an existing finite element model of a bracket is used to demonstrate how to perform direct transient
dynamic analysis using OptiStruct. HyperGraph is used to post-process the deformation characteristics of the bracket under the transient dynamic loads.

This tutorial demonstrates how to set up the random response analysis for the existing frequency response analysis
model. The setup for frequency response analysis is that the flat plate has two loading conditions that will be subjected
to a frequency-varying load excitation using the direct method.
The purpose of this tutorial is to evaluate the vibration characteristics of a half car model subjected to Fluid -
Structure interaction. The fluid that is being referred to is air. Essentially, the noise level or the sound level is evaluated inside the car at a location near the ear of the driver
which is the main response location inside the fluid.
This tutorial demonstrates how to carry out nonlinear implicit small displacement analysis in OptiStruct, involving elasto-plastic materials, contact and continuing the nonlinear solution sequence from a preceding nonlinear
loadcase.
In this tutorial, a modal complex eigenvalue analysis is performed on a simplified brake system to determine whether
the friction effects can cause any squeal noise (unstable modes).
In this tutorial you will perform a brake squeal analysis on a brake assembly. Disc brakes are operated by applying
a clamping load using a set of brake pads on the disc. The friction generated between the pads and the disc causes
deceleration, and can potentially induce a dynamic instability of the system. This phenomena is known as brake squeal.
This tutorial demonstrates how to perform a Response Spectrum Analysis on a structure. This kind of analysis provides
an estimate of peak structural response to a structure subject to dynamic excitation. The analysis uses response spectra
for prescribed dynamic loading and results of normal modes analysis to calculate this estimate.
Computation of the equivalent radiated power (ERP) is a simplified method to gain information about maximum dynamic radiation
of panels for excitations in frequency response analysis. This tutorial demonstrates how to set up the computation request
of ERP on an existing frequency response analysis.
Piston rings fit on the outer surface of a piston in an engine. They support heat transfer from the piston to the cylinder
wall. This tutorial demonstrates running a heat transfer analysis on a set of piston rings.
This tutorial outlines the procedure to perform both 1D and 3D pretensioned bolt analysis on a section of an IC Engine.
The pretensioned analysis is conducted to measure the response of a system consisting of the cylinder head, gasket
and engine block connected by four head bolts subjected to a pretension force of 4500 N each.
This tutorial demonstrates how to set up contact between two parts and the impact of using choosing node-to-surface
(N2S) versus surface-to-surface (S2S). In addition, this tutorial covers how to review the internally created CGAPG
elements in case of N2S, and the nodes in contact in case of S2S.
The OptiStruct Example Guide is a collection of solved examples for various solution sequences and optimization types and provides
you with examples of the real-world applications and capabilities of OptiStruct.
