HyperStudy is the Altair HyperWorks product that performs Design of Experiments (DOE), optimization, and stochastic studies in a CAE environment. HyperStudy lets you study different aspects of a design under various conditions, including non-linear behaviors. You can also study the multi-disciplinary optimization of a design combining different analysis types.
You can use HyperStudy as a stand-alone product or directly from HyperForm from the User Process browser, Process Opti option, which automatically sets up an optimization problem with the following choice of objective functions:
| • | Minimize the distance between the major and minor strain coordinates for each material point in strain space and the curve describing the quality function |
| • | Minimize maximum % thinning |
| • | Minimize maximum plastic strain |
| • | Minimize Springback (multistage setup only) |
| • | Optimize Trim lines (multistage setup only; requires a target boundary line which is a geometry input in IGES format.) |
| • | Optimize Blank shape (multistage setup only; requires a target boundary line which is a geometry input in IGES format.) |
For the above, the constraints can be Maximum thinning or Maximum plastic strain, limited to a user-defined value.
You can choose design variables from a list of potential process variables. You can also choose design variables from a list of shapes created by the HyperMorph module. The entire optimization study is managed by HyperStudy in batch. This support is limited to a one-step solution (HyperForm solver) and the incremental solution (RADIOSS).
Elaborate Optimization Problem Setup
When you access HyperStudy from the Applications menu, you have direct access to the HyperForm database to perform design parameterization. Both solution modes, the one-step solution (HyperForm solver) and the incremental solution (RADIOSS and LS-DYNA) are supported.
| • | For the purpose of defining design variables, only shapes (as created by the HyperMorph module) can be accessed. |
| • | Models can be parameterized using a base input template derived from the ASCII solver input. |
See the HyperStudy online help to learn about setting up and performing studies. Tutorial HF-4020: Optimization 1-Step demonstrates the use of HyperStudy from within HyperForm and explains the quality function.
