    Hi @Minh_169,

    While SimLab experts provides support on the query, I would like to add a point worth mentioning which is related to using custom parameters as design variables for a DOE/Optimization study.

    Using 'Parametrized File' model type in HyperStudy, any value from the solver decks (such as .fem, .rad or .k) such as pitch angle, roll angle, load values etc. can be parameterized as design variables.

    These mentioned design variables might not be available as default parameters in HyperMesh, SimLab etc. & hence, only approach would be to use the 'Parametrized File' model type in HyperStudy for performing a DOE.

    Many thanks.

    Kind Regards

    Hello Minh,

    Can you please provide more details on your model and model setup to help you define the best way. Thank you.

    Kind regards,

    Hi Huyen,

    sorry for the delayed answer,

    this option is quite hidden in the current v2025.
    You should create a DropTest Solution with a drop direction in REVERSED Z AXIS.
    At that point, you will get the options for the pitch/roll angles.
