I am having problems reading CAESAR II neutral files in AutoPIPE. If I create the CAESAR II neutral file in version 4.4, AutoPIPE has no trouble reading the neutral file. However if I create the CAESAR II neutral file in version 4.5 every time I try to open it in AutoPIPE it crashes.

Any suggestions why?

Sure - we added data to the CAESAR II input for Version 4.50.

The "reducer element" section is new, and the "allowable stress" section was expanded.

The Autopipe import routine will have to modified accordingly in order to read in 4.50 CII files.

Thanks Richard,

The model I am actaully converting was originally modelled in CAESAR II version 3.x about 8 years ago, so had none of these flash new features (reducers etc) in it so I hadn't thought about the issue being at the AutoPIPE end.
