software suppliers. Because of unknown current addresses, the following
former customers were not notified:
Reactor Controls, Inc.

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 shown for the full ANSYS
product, starting
at Rev. 5.0, and
beyond, unless
otherwise noted.
PREPPOST contains relevant errors shown the full ANSYS
for product, for
included pre- and
postprocessing
functionality
ANSYS Component Products is an inclusive term for All component
products that were
issued at the
stated revision
level(s)
PC/LINEAR is equivalent to WS/LINEAR at Rev.
4.4A,
and ANSYS/LinearPlus
starting at Rev.
5.0A.
PC/THERMAL is equivalent to WS/THERMAL at Rev.
4.4A,
and ANSYS/THERMAL
starting at Rev.
5.0A.
PC/MAGNETIC is equivalent to ANSYS/Emag
starting at Rev.
5.0A
ANSYS (Registered Trademark) CLASS3 ERROR REPORT
ERROR NO: 95-01
KEYWORDS: SBCDELE SBCLIST EDGE PRESSURES FLUENCES
DESCRIPTION OF ERROR:
1. The command "SBCDELE,APSF" deletes edge pressures from associated
elements in addition to the expected normal pressures.
2. The command "SBCDELE,KT" deletes keypoint temperature
specifications, but not fluences.
3. The command "SBCLIST,KT" does not list specified keypoint fluences
where no keypoint temperature is specified.
FIRST INCORRECT VERSION(S):*_/ CORRECTED IN:*_/
Error 1: Rev. 4.4 Rev. 5.2
Component Products Rev. 4.4 Component Products Rev. 5.2
Error 2 & 3: Rev. 5.0 Rev. 5.2
Component Products Rev. 5.0A Component Products Rev. 5.2
SUGGESTED USER ACTION FOR RUNNING ON UNCORRECTED VERSION:
1. a. Use SFADELE instead.
b. If SBCDELE is already issued, reapply edge pressures previously
applied directly to elements. (Edge pressures from transfer of
line surface loads will be redefined automatically the next
time solid model boundary conditions are transferred.)
2. Use BFKDELE instead of SBCDELE,KT.
3. Use BFKLIST instead of SBCLIST,KT.
COMMENTS:
The SBCDELE command is not documented in ANSYS Rev. 5.0 and Rev. 5.1
and will not be supported in ANSYS Revision 5.2.

*_/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

ANSYS (Registered Trademark) CLASS3 ERROR REPORT
ERROR NO: 95-02
KEYWORDS: DOCU SURF22 SOLID72 SOLID73 PRESSURE
DESCRIPTION OF ERROR:
Applying pressure loads through SURF22 elements to SOLID72 or
SOLID73 elements produces incorrect results. This is due to a
theoretical limitation and cannot be corrected in the program.
FIRST INCORRECT VERSION(S):*_/ CORRECTED IN:*_/
Rev. 5.0 Rev. 5.2 Elements Manual
SUGGESTED USER ACTION FOR RUNNING ON UNCORRECTED VERSION:
Apply pressures directly on the faces of SOLID72 and SOLID73
elements.
COMMENTS:
The documentation in the Elements Manual will be changed to reflect
this limitation.

ANSYS (Registered Trademark) CLASS3 ERROR REPORT
ERROR NO: 95-03
KEYWORDS: MESH VOLUME MIDSIDE NODES
DESCRIPTION OF ERROR:
A volume mesh (VMESH) with 20-noded brick elements (SOLID90 &
SOLID95) can produce incorrect midside node locations wherever an
individual element spans an arc of more than 30 degrees.
Improperly located midside nodes could induce singularities or other
undesired behavior in a solution.
FIRST INCORRECT VERSION(S):*_/ CORRECTED IN:*_/
Rev. 5.0 Rev. 5.2
Component Products Rev. 5.0A Component Products Rev. 5.2
SUGGESTED USER ACTION FOR RUNNING ON UNCORRECTED VERSION:
1. Limit spanned angle per element to 30 degrees (e.g. ESIZE
command):
or 2. graphically verify the locations of midside nodes produced by
VMESH (e.g. EPLOT).
COMMENTS:
Generally, individual elements spanning more than 30 degrees should
not be used in areas where high accuracy is desired.
