  • 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.

  • 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.

  • 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.

  • 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.

  • “Symmetry" 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.

  • "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.

  • 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.

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

  • The value of the global stress goal is missing after upgrading the database from 2020 to 2020 Feature Pack 1 release. If the calculation took place locally, have a look at the Configuration File in the result folder to find the information.

  • 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.

  • The tessellation of exported STL-files might be very coarse.

  • Apex 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.
