                  ANSYS Revision Identifier Description

      ANSYS revision identifiers consist of a major revision level, a
minor revision level, a correction level, and occasionally a special
version level.  An example of how this is constructed is shown below:

                             Figure omitted.

      Major revision level changes indicate that new features have been
added to the program and that some level of program architecture change
and/or file structure has occurred.  Minor revision level changes also
indicate that new features have been added to the program, but files are
upwardly compatible.  All known error fixes are included in both minor and
major revisions.  Changes to the correction level indicate that it is
primarily an error correction release.  Special version identifiers
indicate that one or more additional minor changes have been made to the
program, normally to circumvent an error.  Special versions are not
general releases to all ANSYS licensees, since they typically represent
errors occurring only on one system, a subset of our customers who have
specific graphics devices, etc.

      The ANSYS revision identifier(s) shown under "corrected in" on the
front side of this Class3 Error Report indicates the first possible
revision that could contain the correction.  A major program change needed
to fix an error can dictate that the next minor or major revision will
contain the fix rather than the next correction level.  For example, when
errors were being reported while Rev. 4.3A was the latest production
version, most Class3 error reports indicated that 4.3B was the "corrected
in" revision.  Others requiring significant code restructuring were
reported as fixed in 4.4.  Rev. 4.3B was never released, but Rev. 4.4
contained all error corrections noted as fixed in 4.3B.

      An identifier indicated under "corrected in" does not guarantee that
a general release of that revision of ANSYS will occur.  It does indicate
that the correction is known and implemented in the coding that would be
part of that general release.

                     Equivalent Product Identifiers

      The ANSYS family of component products occasionally undergoes name
changes between revisions and/or changes in the functionality of derived
products (such as ANSYS-PC/LINEAR).  To minimize the potential for
confusion in these areas, the important product name equivalences (similar
program functionality and error content) are listed below.

      ANSYS/ED       contains all errors      the full ANSYS product,
                     shown for                starting at Rev. 5.0, and
                                              beyond, unless otherwise
                                              noted.

      PREPPOST       contains relevant        the full ANSYS product, for
                     errors shown for         included pre-  and
                                              postprocessing

                                                        ERROR NO:  94-61

KEYWORDS:            APDL           COMMENTS IN-LINE


DESCRIPTION OF ERROR:

      The use of the in-line comment character (!) in the 5th to 8th
character position (not including the leading spaces) on the *ELSE,
*ELSEIF, *END, *ENDIF, or *ENDDO commands will result in the whole command
line being taken as a comment line and ignored.

SUGGESTED USER ACTION FOR RUNNING ON UNCORRECTED VERSION:

      Make sure any in-line comments start past the 8th character
      position.

*_/ If a product name is not included in the "first incorrect version",
the full ANSYS program is implied, for products not listed, this error
does not apply, but see the reverse side for equivalent product
designations.

Unless noted otherwise, this error report also applies to all revisions
after the first incorrect one and prior to the corrected revision.  All
revisions after "corrected in" are corrected.  Manual corrections are
included in on-line documentation as appropriate.  Please see the reverse
side of this sheet for additional information on ANSYS revision
identifiers.

            ANSYS (REGISTERED TRADEMARK) CLASS3 ERROR REPORT

                                                        ERROR NO:  94-62

KEYWORDS:  SOLID MODEL B.C.s        DL        LINE           AREA 


DESCRIPTION OF ERROR:

      The normal area specified (AREA) on the operation which applies
symmetry or antisymmetry conditions to a line (DL) is always set to the
default area (lowest numbered area attached to the line), even if a value
(different from the default) is input and echoed to the output file.  A
subsequent listing of solid model loads (e.g. DLLIST) will show the area
number actually used.

      An incorrect setting of AREA could result in improper symmetry or
antisymmetry constraints on the finite element model.

      In Revision 5.0 and Revision 5.0A, this error only occurs when LINE
= "ALL" (all selected lines).  In Revision 5.1, the error occurs for all
forms of input for LINE.

SUGGESTED USER ACTION FOR RUNNING ON UNCORRECTED VERSION:

      1.   Apply the symmetry or antisymmetry constraints directly on
           nodes (D or DSYM operations).

or    2.   Delete any area(s) attached to the line which are numbered
           lower than the desired normal area, (unselecting the area(s)
           is not sufficient)
