We have discovered a problem in FEMAP version 11.2 that users should be
aware of. When opening models or when importing FEMAP Neutral files from
previous versions of FEMAP, CBUSH elements whose property table references
a coordinate system will not be migrated correctly. The problem occurs when
any Neutral File is imported, including the automatic conversion that
happens when opening model files from previous versions of FEMAP.

FEMAP v11.2 added optional element based coordinate system references for
CBUSH elements. When a Neutral File is read, the elements get flagged with
this new option, but the coordinate system reference is still in the
property table and does not get moved to the element definition. CBUSH
elements with an orientation specified using an orientation node or vector
are not affected.

The API at the end of this document will correct the neutral file
conversion error and restore your model to its correct state.

IMPORTANT – There is one special case where this API will not correct all
problems. This special case affects migration of models from previous FEMAP
versions, import of Neutral files, and also affects import of Nastran input
files into FEMAP. This special case occurs if the model being migrated or
imported had CBUSH elements that meet all of the following criteria:

a) The element connects non-coincident nodes, and
b) The element has axial stiffness only, and
c) No orientation is specified for the element, and
d) The element did not reference a coordinate system.

The element x axis of these elements that have no orientation specified
defaults to the vector from node 1 to node 2 in NX Nastran. FEMAP version
11.2 will assign the global coordinate system to these elements, which will
not be correct unless the direction from node 1 to node 2 happens to be the
global x direction. You will have to update these elements manually and
assign a valid orientation.

This problem will be permanently corrected in FEMAP V11.2.1. FEMAP V11.2.1
will be a maintenance release containing several fixes and enhancements.
FEMAP V11.2.1 will also include the upcoming NX Nastran V10.2 release to
keep our FEMAP with/NX Nastran customers up to date. V11.2.1 is currently
scheduled for online availability on or around June 1st, 2015. A separate
SFB will be issued when it is available for download.

Here is the API program to correct models migrated from a previous version
of FEMAP:
