OptiStruct is a proven, modern structural solver with comprehensive, accurate and scalable solutions for linear and nonlinear
analyses across statics and dynamics, vibrations, acoustics, fatigue, heat transfer, and multiphysics disciplines.
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.
A uniform, homogeneous plate which is symmetric about horizontal axes in both geometry and loading, to find the maximum
axial stress in the plate with a hole.
Snap-fit is a combination of two components namely mating and base part which form a mechanical attachment between them
by means of locators, locks and enhancements. Nonlinear Static Analysis with large displacement theory is used to solve
this example.
Contact smoothing is useful to increase accuracy of the contact solution. An enforced displacement to push two concentric
rings toward each other to engage the contact is used. The usage of NLOUT entry allows you to study the progression of SPC force over successive increments.
Demonstrate a revolute joint using JOINTG and MOTNJG. The JOINTG entry can be used for defining a variety of joints, including revolute, ball, universal, cardan, and so on. Motion on
these joints can be applied using the MOTNJG entry.
The PCOMPLS entry can be used to define continuum shell composites using solid elements. Currently first order CHEXA and CPENTA solid elements are supported.
Demonstrates self-contact which is used in this nonlinear large displacement implicit analysis involving hyperelastic
material and contacts using OptiStruct.
This section presents optimized topology examples generated using OptiStruct. Each example uses a problem description, execution procedures, and results to demonstrate how OptiStruct is used as a design concept tool.
This section presents size (parameter) optimization examples solved using OptiStruct. Each example uses a problem description, execution procedures, and results to demonstrate how OptiStruct is used in size optimization.
This section presents shape optimization example problems, solved using OptiStruct. Each example uses a problem description, execution procedures and results to demonstrate how OptiStruct is used in shape optimization.
The examples in this section demonstrate how topography optimization generates both bead reinforcements in stamped
plate structures and rib reinforcements for solid structures.
The examples in this section demonstrate how the Equivalent Static Load Method (ESLM) can be used for the optimization
of flexible bodies in multibody systems.
