However, the ANS file is incomplete, so until they're the same, we'll document it.

**What is the difference between F06, OP2, and NEU files?**

**F06** is the main human readable Nastran/Mystran output. It contains error messages, warnings, etc. which can make things harder to parse. In general, you'd use this for quick checks, but post-processors like FEMAP / PATRAN / pyNastran can't read it. An F06 result is requested with a PRINT flag.

The **ANS** is LINK9 (results) only and requires a debug flag to export. It is simpler to parse, but basically the same as the F06. An ANS result is requested with a PRINT flag and a ``DEBUG,200,1`` flag.

THe **OP2** is the main binary output file that FEMAP / PATRAN / pyNastran can read. An OP2 result is requested with a PLOT flag (e.g., ``DISP(PLOT) = ALL``).

5753
The **NEU** is an ASCII file that is supported by FEMAP. It's not well tested against though. NEU is selected with the ``PARAM,POST,-1`` flag.
