Steps for creating a Mechanical problem for structural optimization
The tools used to describe a Mechanical problem for optimization are accessible through the Solver → Optimization → Mechanical optimization branch of the Data tree, as shown in Figure 1
Figure 1. The tools for creating a Mechanical problem for optimization in the Flux 2D Data Tree (highlighted inside the red rectangle).
The steps for creating a Mechanical problem for optimization are the
following:
- Define one or more Mechanical regions.
- Define one or more Mechanical boundary conditions
- Using the previously created Mechanical regions and Mechanical boundary conditions entities, create the Mechanical problem.
Steps 1 to 3 above are detailed in the next sections.
Important: Once the Mechanical problem has
been created, it must be integrated to the description of an Optimization
problem. The Optimization problem must also contain one or more
Mechanical responses in its description to benefit from the
Mechanical problem definition. The Constraints describing the
Optimization problem may also derive from Mechanical responses
under those circumstances.
Remember:
Mechanical responses may be created by clicking the Responses node
of the Data tree and by selecting the option Mechanical response
in the Physical quantity to optimize drop-down menu. There are two
subtypes available, namely:
- Von Mises stress and
- Compliance.
