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.

In this tutorial you will perform a shape optimization on a cantilever beam modeled with shell elements.

In this tutorial you will perform a shape optimization on an L-section cantilever beam modeled with shell elements.

In this tutorial you will perform a shape optimization on a solid bracket model using the Free Shape optimization method. The objective of this optimization is to reduce the stress by changing the geometry of the bracket model.

In this tutorial, you will perform a size and shape optimization on a structural rail to increase the buckling factor, thereby increasing the load it can carry before buckling. The rail has external forces applied at one end, and is constrained in all degrees of freedom at the other end. By performing buckling optimization, the buckling factor can be increased and thereby increase critical buckling force.

In this tutorial you will perform a shape optimization on a rail-joint. The rail-joint is made of shell elements and has one load case. The shape of the joint is modified to satisfy stress constraints while minimizing mass.

In this tutorial you will set up the structural optimization problem of MBD systems with HyperMesh, and run the shape optimization job in OptiStruct.

In this tutorial you will perform a shape optimization on a solid model using the free-shape optimization method along with manufacturing constraints, such as symmetry and mesh barrier constraints. The objective of this optimization is to reduce the stress by changing the geometry of the model.

In this tutorial you will perform a free-shape fatigue optimization on a torque control arm. The objective of this optimization is to increase the fatigue life of the control arm by changing the geometry of the model.

In this tutorial you will perform a Global Search Optimization (GSO) with shape design variables.

In this tutorial you will perform a shape optimization on an example of aluminum fins.
