Substructures and Submodeling with Abaqus

Providing effective techniques that allow the analyst to study problems that are too large to simulate with a conventional modeling approach

Course Objective

The size and complexity of designs that are analyzed and tested with Abaqus continues to grow. Substructures and submodeling are two effective techniques that allow the analyst to study problems that are too large to simulate with a conventional modeling approach.

Substructures are useful to break a large problem into several smaller components. The substructure lectures teach users how to:

Maximize CPU savings when using substructures
Translate, rotate and reflect substructures when using multiple copies in a problem
Build preloads into substructures
Plot results within substructures
Use substructures in dynamic simulations
Use substructures when the problem contains nonlinearities, such as contact
Using co-simulation techniques to include substructures in Abaqus/Explicit

The submodeling lectures cover the following topics:

When submodeling can be useful
The proper design of a coarse, global analysis that can "drive" the submodel analysis
Mesh design for the submodel analysis
Shell-to-shell and shell-to-solid submodeling
Solid-to-solid submodeling
Submodeling in nonstructural problems
