Highlights


HyperStudy 14.0 provides several exciting new features that enable users to explore designs more thoroughly and efficiently than ever before.  From quickly picking your design parameters in HyperMesh to a new streamlined response definition experience, getting HyperStudy setup to run your investigation has never been easier.   The new inclusion matrix allows optimizers to utilize existing run information, increasing the optimizer’s efficiency and making the most out of your data.  The automatic cross-validation check can save time by calculating checks on the Fit quality without a dedicated validation matrix.

 

hmtoggle_arrow1Inclusion Matrix

The inclusion matrix enables optimizers to optionally accept available run data as an input.  This can save significant time during the optimization process, as the optimizer can utilize previously run data.   This inclusion data typically comes from previously run approaches, for example, DOE or another optimization, meaning users are empowered to make sure no run data is left unused when optimizing.

 

hmtoggle_arrow1File Assistant Wizard to Build Responses

The File Assistant Wizard lets you select a target file, and a guided set of dialogs produces a completely defined response.  This efficient process simplifies the response creation steps by moving the response construction syntax of the expression builder to the background.

 

hmtoggle_arrow1Parallel Coordinate Plots

Parallel Coordinate Plots, also known as Snake Plots, have a dedicated tab in each approach’s post-processing.  The plots feature controls to only show subsets of variables and responses as well as window filters to visualize areas of interest.  These versatile plots are very effective in mining information from large data sets.

 

hmtoggle_arrow1Extended HyperMesh Parameterization

User created parameters in HyperMesh are expanded to include the Abaqus, Nastran, and RADIOSS user profiles.  These parameters can be imported by HyperStudy from HyperMesh models as design variables.

 

hmtoggle_arrow1Cross-Validation Introduced in Fit Post-Processing Diagnostics

Cross-validation is a technique used to assess the Quality of a Fit without requiring a validation matrix.   This feature is now automatic on all Fit types in HyperStudy.  While a dedicated validation matrix is still suggested for more complete checking, this time saving calculation can provide quality information, when a validation matrix is not available.

 

hmtoggle_arrow1Filtering Out Data in Fit Approaches

Including data gaps, duplicates, or outliers when building a Fit can lead to poor quality results.  New data filters automatically clean up data sets without manual intervention, helping ensure the Fit is not biased by bad data.  

 

hmtoggle_arrow1Other Enhancements
New SimLab model type.
New FEKO model type.
Fit tradeoff tabs redesigned providing an intuitive and efficient results browsing experience.
Fit quality metric introduced to dynamically track extrapolation.
Histogram and Box Plots merged into Distribution tab.
Discrete variable support has been extended within the user interface.
A uniform distribution is now available for discrete variables.
Introduced the Editor option to visualize fixed field demarcation lines.
New database to handle larger data sets.
P-values available in least squares regression diagnostics and ANOVA tables.
Autobuild for Fit is removed as an option; the Fits will always be built.
Table cells now support the display of string variables values.

hmtoggle_arrow1Resolved Issues
The execution status of runs when multi-execute is enabled has been updated
The tooltip on the Optima tab now presents updated information
Precision loss of importing data into Fit is addressed
Improved speed and performance of switching plots
Safe opening of a running study with a second HyperStudy occurrence is supported
Fixed issues with using relative paths and MotionSolve models
Fixed a memory issue when starting HyperStudy from HyperMesh
Corrected matrix size calculation when creating a Full Factorial DOE with linked variables

 

hmtoggle_arrow1Known Issues
An indexing change in the structure of stress results read by 14.0 products could impact responses defined in older studies.  Responses built using expressions like resvector, which use indexed values, will require a different set of indices when compared to previous versions.  Newly defined responses will not be affected.
