i have dataset ansys result file and i am trying to to make data set for result prediction but some error is coming while extracting dataset error image attached

please give me detailed error solution don't say like you have inconsistent dataset or some silly things

    Hi @yash201,

    PhysicsAI requires consistent data (result files) for the model training, testing & prediction.

    Consistent data infers same number of loadcases, loadcase name, component names etc. 

    Since, the files that are being used in PhysicsAI for dataset creation are having either no common loadcase or the loadcase/subcase names are not consistent across the files, the mentioned error is there.

    Hence, make sure that the files being used in PhysicsAI for dataset creation are having common loadcase having same naming convention througout.

    Many thanks.

    Kind Regards

    thank you so much for your kind response

    I would like to inquire about which naming conventions should be made consistent. For instance, if I have an ANSYS RST file, should I use the same naming conventions in the ANSYS file, the RST file, and the load case (such as geometry name, fixed support name, and force name)?

    Hi @yash201,

    PhysicsAI reads binary results file (such as .h3d/.rst/odb) as an input for the training dataset. Hence, the loadcase naming should be same across all the Ansys result files (.rst) that you intend to use in PhysicsAI.

    If you have any further queries related to PhysicsAI, it is recommended to mail us on hwsupport@altair.com to get a timely response.

    Many thanks.
