Fixed Bugs & Known Limitations

Fixed Bugs:

  • Terminating an optimisation in the first few iterations on GPU is no longer causing a hang/crash.

  • Per default the Complexity cannot exceed available memory. As a workaround one can add an Advanced User Setting.

  • MSC Apex Generative Design might produce different results for the same model in different orientations.

  • MSC Apex Generative Design will not consider Pressure Loads when activating the Advanced User Setting command: automaticFunctionalFacesDetection.positiveNondesignDirection=false. This combination of input is not supported by the algorithm. As a workaround the additional Advanced User Setting command can be deleted.

  • Machining allowances selected with the GD Configuration Tool might not be the same geometries as before. As a workaround the machining allowances can be created manually on the newly created Design Space.

Known Limitations:

  • The material coordinate system is without function. The global coordinate system acts always as the material coordinate system. The global x-axis is always the build direction. As a workaround the part can be aligned using the Transform Tool.

  • Remote submittal of simulation for Linux is not supported in MSC Apex Generative Design release 2021.2. However, one could use command line submittal of Optimization jobs on both Linux and Windows and import the results into the application. For more information on Command Line Optimization; please see: Generative Design - Command Line Optimisation

  • MSC Apex Generative Design might not visualize Non-Design Spaces using the Shape Quality “Preview”. The Non-Design Spaces are considered in the optimisation but because of the coarse resolution level of these iterations not visualized (fully). Choose another Shape Quality setting to run a complete optimisation and receive a full visualization.

  • "Restart" is not directly selectable in the User Interface but is available for the optimisation as an unsupported option using the Advanced User Settings. For more information have a look here.

  • The simulation may fail using a remote solver due to the case sensitivity of the machine name.

  • You might not be able to zoom in the stress chart view in Post.

  • MSC Apex Generative Design may not start up due to the presence of wide-characters in the program path. Please change the location of the program to a path without any wide characters.

  • While uninstalling MSC Apex Generative Design some files might not be removed.

  • Machining allowances selected with the GD Configuration Tool might not be the same geometries as before. As a workaround the machining allowances can be created manually on the newly created Design Space.

  • If Retained Volumes are included, the mass is estimated based on the different densities of the volumes.

  • When using the GD Configuration Tool, loads and boundary conditions placed on the original parts Non-Design cells will not be transferred to the created Design Space. Please create the loads and boundary conditions after creating the Design Space with the GD Configuration Tool.

  • An optimisation which uses only 1 CPU Thread cannot be executed. Please adjust the number of CPU Threads in the Application Settings - Generative Design Solver or in case of a Command Line Optimisation in the Configuration File.
