In addition, a connector’s connector control can become a design variable, allowing different controls to be used for a given connector within an exploration. Finally, a new connector response, the total number of connectors, has been provided. This response can be used as an optimization objective to minimize the number of connectors used.
Results compare contour
A new comparison contour has been added to the Results Explorer. You can select and compare any two runs in an exploration. The comparison plots the difference in design variables as a bar chart and also contours the changes onto the model graphics, allowing for easy visualization of the design variable changes.
Machine learning enhancements
Clustering
A new AI report has been added to the Scatter Plot tool in the Results Explorer. You can now automatically group exploration results into clusters, classifying based on different criteria. This can be useful in cases where you want to view or choose designs based on a certain classification, such as deformation mode.
Field prediction performance
