the attached file possess a direct frequency response analysis setup, the solver is stuck since many hours, can you plz check the file if i have missed something. the file isnt too big.
Hi Muhammad,
Could you please try to run the Modal FRF instead of Direct FRF, for cases like this, it is more suitable. Please switch the analysis type to MFRF and add the EIGRA card under METHOD(STRUCTURE) entry. I see that the FRF goes up to 200Hz, so setting V2 = 300Hz under EIGRA should be fine. I did a test here and using this approach your model ran in 7 minutes (using 16 cores).
If this works for you, please consider marking this answer as correct to help others.
Thanks,Vinicius
