OptiStruct for Linear Analysis (1) Course Overview

 

 

Course Summary

OptiStruct has the ability to perform many types of Linear Analysis.  In this course, you will have the opportunity to learn how to use HyperWorks to set up a Linear Analysis for OptiStruct. Modules contained within the course provide detailed descriptions of some of the types of Linear Analysis available. You will also have the opportunity to watch demonstrations and perform hands-on exercises throughout the modules.

Course length approximately 9 hours

Course Agenda

In this lesson, we will cover the course agenda.  This course will look at the available analysis types in OptiStruct, as well as familiarize us with the elements, materials, loads, and boundary conditions for linear statics in OptiStruct.  We will set up the following analysis types:  linear static, inertia relief, normal modes, buckling, and thermomechanical.  Watch the video below to learn more!

 

OptiStruct Overview

In this lesson we will take a look at OptiStruct.  Altair OptiStruct is an industry proven, modern structural analysis solver for linear and non-linear structural problems under static and dynamic loadings. It is the market-leading solution for structural design and optimization.  Based on finite-element and multi-body dynamics technology and through advanced analysis and optimization algorithms, OptiStruct helps designers and engineers rapidly develop innovative, lightweight and structurally efficient designs.  OptiStruct is used globally at industry-leading companies to analyze and optimize structures for their performance including e.g., strength, durability and NVH (noise, vibration and harshness) characteristics.   Watch the video below to learn more.

OptiStruct Analysis Features Overview

OptiStruct (OS) is a finite element and multi-body dynamics solver which can be used to design and optimize structures and mechanical systems. The graphical interface for OS within HyperWorks allows you to perform complete modeling, optimization problem setup, job submission, and post-processing quickly and easily.

The following analyses are supported.  We are going to focus on the basic analysis features in this course.

Basic Analysis Features

• Linear static 
• Normal modes
• Linear buckling 
• Thermal-stress steady state 

Advanced Analysis Features

• (Direct and Modal) Frequency response function (FRF) analysis
• Random response analysis
• (Direct and Model) Transient response analysis (Fourier method)
• Non-linear contact analysis
• Acoustic Analysis (Structure and Fluid)
