Please check the .dat, .msg, and .sta files for error messages if the files
exist.  If there are no error messages and you cannot resolve the problem,
please run the command "abaqus job=support information=support" to report and
save your system information.  Use the same command to run Abaqus that you
used when the problem occurred.  Please contact your local Abaqus support
office and send them the input file, the file support.log which you just
created, the executable name, and the error code.
