Fixed Bugs:

  • MSC Apex Generative Design supports one material for all spaces. As a workaround unsupported options can be added using the Advanced User Settings to define different materials.

  • MSC Apex Generative Design may ignore boundary conditions if a pressure load as well as other conditions are applied on the same surface. Pressure loads can only be applied on the specific surface where no other boundary conditions are active.

  • MSC Apex Generative Design might generate results that use material outside of the Design Space. This only happens for small features and is depending on the chosen complexity. As a workaround the component generating this behaviour can be deactivated by writing the following command in the Advanced User Settings: MorphologicCorrection.

  • MSC Apex Generative Design might not consider the Event Specific Stress Goal order correctly. As a workaround an Event Specific Stress Goal for each Event needs to be set.

  • MSC Apex Generative Design might generate different results while calculating in different unit systems due to inaccuracies/differences of decimal places.

  • MSC Apex Generative Design supports one solid using the User Interface. As a workaround the command line optimisation input can be influenced and multiple solids realised.

Known Limitations:

  • When using Symmetry, the translational displacements may be plotted incorrectly on the result geometry. They might be plotted according to the symmetry coordinate system and not according to the global coordinate system. However, the displacements are considered correctly during the calculation and design generation - just the visualization in the post processing is impacted.

  • Remote submittal of simulation is not supported in MSC Apex Generative Design release 2021.1. 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:https://amendate.atlassian.net/l/c/Rg3koDNE

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

  • 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 might produce different results for the same model in different orientations.

  • 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.

  • 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.

  • 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.

  • Parallelisation of GPUs is not supported in this release.
