Fixed Bugs & Known Limitations

Bug fixes:

• MSC Apex verification workflow: The material information in case of orthotropic material behaviour are transferred to Apex so that the information fit to the global coordinate system instead of the build direction in Generative Design.

Known Limitations:

• In case of anisotropic material stiffness and the directional dependent Tsai Wu transeversely isotropic Failure Criterion with widely spaced values, the optimisation may not give stable results. 

  For a better result, the Tsai-Wu 3D orthotropic Failure Criterion should be used (available with the Advanced User Settings). Please have a look here for further information.

• Remote submittal of simulation for Linux is not supported in MSC Apex Generative Design release 2023.1. 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: Generative Design - Command Line Optimisation

• MSC Apex Generative Design might not visualize Non-Design Spaces / Interfaces using the Shape Quality “Preview”. The Non-Design Spaces / Interfaces 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.

• 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.

• 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.

• When the interface thickness ≥ offset distance then the interface volume will be hidden in GUI due to a current limitation. The optimization will still consider the entered values and the Print Geometry will consider the entered Machining Allowance value.

• If a symmetry Design Space is created, changing/updating the Principal Coordinate System afterwards doesn’t have any impact on the symmetry coordinate system and thus no impact on the used coordinate system for the optimisation.

• If anisotropic material behaviour was used and the build direction was changed inside the optimisation scenario in the studies tab, the rotated material orientation won’t be transferred to Apex Structures for the Re-Analysis. The material orientation needs to be checked and adjusted accordingly.
