Imported imperfections are wrong

BamertD · Oct 19, 2023

I am doing a GMNIA on an I profile but for some reason the imported imperfection(.FIL file) from my LBA does not match the imperfection shape that my LBA found.
It is weird because the overall shape seems to be correct, but the edge elements of the web are off by quite a lot.

i am generating the INP files for the LBA and GMNIA in different python scripts.
Any ideas as to why this could happen?

Which mode shape(s) and with what scale(s) did you use ? Can you show the deformed shapes from both analyses overlaid on each other ?

Thank you for your interest in helping me. The error was that i duplicated the command *BOUNDARY in the GMNIA inp file.
Very strange that it influenced the imperfection like this. But happy i was able to resolve the issue.
