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.

OS-E: 0160 Nonlinear Static Analysis of Snap Fit Assembly Using Continuous Sliding

Demonstrates the effect of continuous sliding in Nonlinear Static (large displacement)
Analysis.

Continuous sliding allows for the incorporation of continuous (large) relative sliding
between the main and secondary. Contact is updated for every iteration. Continuous sliding
contact is expected to produce more accurate results and, in some cases, better convergence
robustness, especially when very large sliding and/or distortion are present.
