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.
Elements are a fundamental part of any finite element analysis, since they completely represent (to an acceptable
approximation), the geometry and variation in displacement based on the deformation of the structure.
The different material types provided by OptiStruct are: isotropic, orthotropic, and anisotropic materials. The material property definition cards are used to
define the properties for each of the materials used in a structural model.
High Performance Computing leverages computing power, in standalone or cluster form, with highly efficient software,
message passing interfaces, memory handling capabilities to allow solutions to improve scalability and minimize run
times.
Contact is an integral aspect of the analysis and optimization techniques that is utilized to understand, model, predict,
and optimize the behavior of physical structures and processes.
This solution sequence performs static nonlinear analysis. Static inherently implies that a process
occurring in real-time is being simulated infinitely slowly.
This newly developed OptiStruct Explicit solution type (ANALSIS=NLEXPL) has been developed solely in OptiStruct, in the same way as the OptiStruct implicit solution. The input data (elements, material, property, loading, and so on) for explicit solution is the
same as implicit solution and the output data structure is also the same as implicit solution.
Normal Modes Analysis, also called eigenvalue analysis or eigenvalue extraction, is a technique used to calculate the vibration shapes and associated frequencies that a structure will exhibit.
Response Spectrum Analysis (RSA) is a technique used to estimate the maximum response of a structure for a transient
event. Maximum displacement, stresses, and/or forces may be determined in this manner.
Calculates the response of a structure to time-dependent loads. Typical applications are structures subject to earthquakes,
wind, explosions, or a vehicle going through a pothole.
Nonlinear Small Displacement Transient and Nonlinear Large Displacement Transient (LGDISP) Analysis are currently available
to solve nonlinear problems which include transient effects.
OptiStruct and AcuSolve are fully-integrated to perform a Direct Coupled Fluid-Structure Interaction (DC-FSI) Analysis based on a
partitioned staggered approach.
Aeroelastic Analysis is the study of the deflection of flexible aircraft structures under aerodynamic loads, wherein
the deformation of aircraft structures in turn affect the airflow.
OptiStruct provides industry-leading capabilities and solutions for Powertrain applications. This section aims to highlight OptiStruct features for various applications in the Powertrain industry. Each section consists of a short introduction, followed
by the typical Objectives in the field for the corresponding analysis type.
This section provides an overview of the capabilities of OptiStruct for the electronics industry. Example problems pertaining to the electronics industry are covered and common solution

OptiStruct generates output depending on various default settings and options. Additionally,
the output variables are available in a variety of output
formats, ranging from ASCII (for example, PCH) to binary files (for example,
H3D).
A semi-automated design interpretation software, facilitating the recovery of a modified geometry resulting from a
structural optimization, for further use in the design process and FEA reanalysis.
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.
Linear Buckling Analysis
The problem of linear buckling in finite element analysis is solved by first applying a reference level of loading, , to the structure.
Nonlinear Static Analysis
This solution sequence performs static nonlinear analysis. Static inherently implies that a process occurring in real-time is being simulated infinitely slowly.
Explicit Dynamic Analysis
This newly developed OptiStruct Explicit solution type (ANALSIS=NLEXPL) has been developed solely in OptiStruct, in the same way as the OptiStruct implicit solution. The input data (elements, material, property, loading, and so on) for explicit solution is the same as implicit solution and the output data structure is also the same as implicit solution.
Normal Modes Analysis
Normal Modes Analysis, also called eigenvalue analysis or eigenvalue extraction, is a technique used to calculate the vibration shapes and associated frequencies that a structure will exhibit.
Complex Eigenvalue Analysis
Real eigenvalue analysis is used to compute the normal modes of a structure. Complex eigenvalue analysis computes the complex modes of the structure.
Random Response Analysis
Used when a structure is subjected to a non-deterministic, continuous excitation.
Response Spectrum Analysis
Response Spectrum Analysis (RSA) is a technique used to estimate the maximum response of a structure for a transient event. Maximum displacement, stresses, and/or forces may be determined in this manner.
Linear Transient Analysis
Calculates the response of a structure to time-dependent loads. Typical applications are structures subject to earthquakes, wind, explosions, or a vehicle going through a pothole.
