error occurred while using PhysicsAI to predict the drop test analysis
I ran a drop test simulation in SimLab and exported the .h3d file to train a PhysicsAI model in HyperMesh.
However, after completing the training and testing process, I was unable to generate predictions using the new model. Could you please help me check the issue? (The .h3d file is located in the link below.)

Hi @Minh_169,
Thank you for testing the recommendation.
The error when using OptiStruct solver profile indicates that the the input file (.rad) being used for prediction has the below listed components (Board, RightFlexSnap, CoverRear, Connector) which are not there in the training dataset.
Hence, kindly use the input file (.rad) for prediction which has the components mentioned in the error such as Clip_1, Clip_2, Connector1, CoverRear1 etc.
I infer that the some components are new in the input file (.rad) & some have different naming convention. So, kindly make sure that the component number & component naming is consistent across the training, testing & prediction datasets.
Note: This is a generic error & not related to using OptiStruct solver profile. Since, you get another error now, it proves that the 'Predict' step worked but the process failed due to component inconsistency.

Hi @Minh_169,
The issue is known & is related to using 'Simulation Properties' for Prediction in the RADIOSS solver interface in PhysicsAI 2025.0 version.
Workaround is to either use PhysicsAI 2024.1 version or change the solver interface from RADIOSS to OptiStruct after importing the input file for prediction.
If you get an error after updating the solver profile, then, using PhysicsAI 2024.1 version is the only workaround. Unless, you want to use 'Global hooks' approach for adding the simulation properties (thickness/material ID) as inputs in PhysicsAI 2025.0 version.
Many thanks.
Kind Regards

I’ve tried switching the solver interface from RADIOSS to OptiStruct in both the 2025 and 2024.1 versions, but the same error occurred. Could you help me resolve it?
Thank you so much.
