Inspire non-deserialized results and PhysicsAI
Dear community, I have fully parametrized a pressure vessel using Inspire to generate lots of data through DesignExplorer to create a PhysicsAI project. Although, the DoE result files are in a deserialized format, such that each run of the DoE is broken into 6 different "optiResHvtransOut.h3d" files. Is it okay to feed…

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.)

Inconsistent confidence score while using shell and solid mesh for prediction using PhysicsAI
I am using a PhysicsAI model which is trained on linear static FE analysis for making predictions on new mesh data. The model has three components which are connected using equivalence of nodes. (For direct prediction on CAD, I am getting low confidence scores like -60 and that's why I am using mesh for prediction.) While…
