Design Exploration

Adjoint

  • Adjoint sensitivities for global parameters used in 3D-CAD
    • Easily evaluate sensitivities of CAD parameters by introducing the computation of adjoint sensitivity for global parameters used in 3D-CAD​
      • Leverages the Compute Parameter Sensitivity functionality of the adjoint solver, released in version 2306​
      • Requires Geometric Sensitivity mesher enabled and set up for the parameters of interest​
      • Sensitivities are accessible via the sensitivity operator​
  • Per-surface subgroup functionality for surface sensitivity computation
    • Focused optimization of design components by leveraging the Per-Surface subgrouping for the computation of sensitivities​
      • Applicability for CAD parameters and SQP gradient-based optimization​
        • When a boundary is set to active, a new Active Surface Sensitivity node allows users to define the option Displacement or Fixed via sub-grouping​
        • Sensitivity of CAD parameters is only computed when the active condition is Displacement​
      • Applicability for Surface sensitivity computation​
        • In Surface Sensitivity Filter Parameters, Fixed Surface is renamed to Excluded Surface​
        • If the filter option is set to Excluded Surface, surface sensitivities are zeroed​
  • New field function operator clamp(x_min, x, x_max)​
    • Easily constrain adjoint parameter optimizations with a new field function operator
    • Returns x_min or x_max when x is out of the range (x_min, x_max)​
    • The operator is differentiated to be compatible with adjoint workflows​

Design Manager

  • Reuse previous Designs
    • Accelerate turnaround time by leveraging existing results from a previous design.
      • Automatically initialize the next design with the result of the closest available design
        • Based on a parameter space distance
      • Easily identify reused designs and designs reusing results with specific Design Sets
    • Available for Sweep, Design Of Experiment and Optimization studies
  • Clear History
    • Design focused results visualization by removing the initialization related history
        • Reduce likelihood of misinterpretation of results by focusing only on the relevant information
        • Store only necessary data over time
        • Particularly useful when used with the "Reuse previous designs” feature
        • Supports monitor and plots
