Hi, I have a bdf which was created with Patran 2014, but my university has Patran 2016, and everytime I try to import it I get the error Creating Nastran Database using SOL nifimp_v22: Failed but continue. I feel the old formatting of the bdf is not letting Nastran properly read my bdf.
There can be a number of reasons for getting this message. The first thing to try is to answer "no" when it comes up. This should leave a number of diagnostic files in the working directory (.f04, .f06, .log). Check the .f06 file for FATAL errors; that should give an indication of what the problem is.
