WHAT IS THE SSSALTER LIBRARY?

The sssalter library contains a collection of dmap alters that were written either in reponse to client requests or prototypes to demonstrate the feasibility of proposed new features.

While each DMAP alter was tested for a number of possible applications, these alters have not undergone the extensive testing required to be included in MSC.Nastran. It is possible that your application may use a path through the DMAP alter that was not tested, so always review your results carefully. These DMAP alters were developed independently, and it is likely that a conflict will occur if more than one alter is used in a run.

A detailed description of each alter (*.rdm) is delivered with Version 2005 under the sssalter library subdirectory. The sssalter library is located in the

install_dir/msc2005/nast/misc/sssalter

subdirectory. A logical symbol SSSALTERDIR points to this subdirectory. Refer to the MSC.Nastran Installation and Operations Guide for further details.

The naming conventions for the Version 2005 files are shown in the table below.
