Using EIGVSAVE/EIGVRETRIEVE for Random Respone analysis

Question

Hi,

I was wondering if anyone has managed to successfully use the modes calculated in a modal analysis as an input for a random response analysis. Every time I try to run it, I get an error saying “current model does not match the database from the EIGVSAVE”. This is despite using the exact same model.

Thank you.

unless I get the full model, it is difficult to answer what exactly is the cause of the error.

One thing I can say you have defined the options correctly.

Did you get the .eigv file?

Please share the .out file of the run.

Frequency_v18_retrieve_test.fem

Modal_v18_EigenRetrieve.fem

These are the files I have for trying to run it with a modal frequency analysis. I haven't added the model file as it's customer data but it's input in the same way as in these files.
