Features

Nastranfind performs a case-insensitive text research over the whole 'INCLUDE' hierarchy of a given FEA model.

It returns results for the whole FEA, not limited to a given file and/or directory.

Capabilities

• Nastranfind can find the exact location of a given Nastran deck entry
• Nastranfind can check the connections between deck entries, as well as the missing or duplicate entries
• Nastranfind can verify if the INCLUDEs are correctly linked
• Nastranfind can compare two FE models (require to open two consoles)

...and it does these nice things with very large FE Models that contain 1,000,000 elements and more.
