Hi guys, Does anybody know where i can find info about the NASTRAN op2 file structure. I want to write a code to read OP@ files. Where to start. Any ideas?
Cosmic Nastran used to publish Nastran Programmers Manual where they will show the OP file structure. MSC has changed the structure and I could not read it using the Cosmic file structure.
MSC Programmers Manual seems to be outdated becaue it covers version 68.2.3R2. I do not believe MSC publishes a manual for their current release.
this is where I found it:
I am also interested accessing what is in the OP2 file.
Another option might be to output the OP2 in ascii-format instead of binary-format. then you can write an interpreter against the ascii-format.
