HyperStudy allows you to perform Design of Experiments (DOE), optimization, and stochastic studies in a CAE environment. It
allows you to study the different aspects of a design under various conditions, including non-linear behaviors. It
can be applied in the multi-disciplinary optimization of a design combining different analysis types.
In the 2020.1 release, MotionSolve has
new capabilities for optimizing multibody systems.
Optimization is a process by which certain variables of a
system are varied to achieve desired system behavior. The variables that are varied are called
Design Variables (DVs). The system outputs that are monitored are called Response Variables
(RVs). An optimized system is achieved when a design is found that minimizes Response
Variables known as Objectives while satisfying Constraints that also defined with Response
Variables.
To perform system optimization, you first create a nominal working model with a
known initial design and then proceed to execute an Optimization Study that involves five
steps:
The above steps are encapsulated in the Optimization Wizard in MotionView2020.1. This wizard provides an intuitive and step-by-step approach to
performing the above steps. The Optimization Wizard can be accessed by right-clicking on
Model in the Project Browser and choosing
Optimization Wizard.
Once launched, the Optimization Wizard (shown below) guides you with the setup
and solution of the optimization problem in a step-by-step manner.
The wizard ensures that you will complete steps in a specific order. You cannot
move to the next step without completing the current step. The state of each step is
indicated by one of the symbols shown below.
A red cross indicates that this step cannot be accessed; you have to complete
the previous step(s) to perform this action.
An empty check box indicates that this is the current step that you are
working on.
A green check mark indicates that this step has been sufficiently completed
and you can proceed to the next step.
Additional information about each step is provided in the following
sections.
Design Variables
The first step in the Optimization process is to identify the Design Variables (DVs) in your model.
Responses
The Responses step of the wizard allows you to add Response Variables (RVs) to an optimization study.
Optimization Setup
The Optimization Setup step allows you to set up objectives and constraints in the Optimization Study.
Solution
The Solution step of the wizard allows you to specify optimization and simulation settings and perform an optimization run.
Review Results
The Review Results step of the wizard allows you to review the results once the optimization solution has successfully completed.
