Dear Sir or Madam:
In accordance with the reference correspondence and 10 CFR 21, Boeing is
sending the NRC the attached error notice(s) received from our former
software suppliers. Because of unknown current addresses, the following
former customers were not notified:
Reactor Controls, Inc.
Echo Energy Consultants, Inc.
Nuclear Applications and Systems Analysis Company (Japan)
Nuclear Power Services
Tenera Engineering Services
Error notices have been sent to our other former customers.
Very truly yours,
Sandra J. Andrews

Dear Class3 Error Recipient:
Enclosed with this letter you will find ANSYS Class3 Error Reports
96-01, 96-02, 96-03 and ANSYS QA Notice QA96-01. For your convenience,
Class3 Error Report Summaries have been created for Rev. 5.1 and Rev.
5.2 and are also enclosed. These summaries are sorted by Class3 Error
Number and also by keyword.
Throughout 1995 you should have received Class3 Error Reports 95-01
up to and including 95-63. ANSYS QA Notices QA95-01 through QA95-10 were
also issued throughout the year. There was a need to revise some reports
this year and the following reports were also released: 93-105 R1, 94-41
R1, 94-52 R1, 94-68 R1, 94-01 R1, 95-10 R1, 95-07 R1, 95-21 R1 and 95-13
R1.
If you are missing any of the above referenced reports please notify
Bonny Podolek at 412-873-2858 and the missing reports will be supplied to
You. Please take a moment also to review the ASC name and address that
the reports are being sent to. If any changes should be incorporated
into the address, please fill out the form attached to this letter and
return it so that we can update our records.
I would like to remind you that Class3 Error Reports and the Class3
Error Summaries are also available in ascii format via Internet.
like to be added to the distribution list to receive reports in this
fashion, simply send an email to bpodolek@ansys.com and include your
email address, your name, company name and ANSYS license number. Reports
sent via Internet do not replace the hard copy reports. The hard copy
reports are still considered to be the official report.
On behalf of the ANSYS, Inc. staff, I would like to extend to you
and your associates, warm wishes for a prosperous year in 1996.
Sincerely,
ANSYS, 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 in included in both minor and
major revisions. Changes to the collection 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 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.
PC/LINEAR is equivalent to WS/LINEAR at Rev. 4.4A,
and ANSYS/LINEAR starting
at Rev. 5.0.
PC/LINEAR is equivalent to WS/THERMAL at Rev. 4.4A
and ANSYS/THERMAL starting
at Rev. 5.0.
PREPPOST contains relevant the full ANSYS product,
errors shown for for included pre- and
postprocessing
functionality

ERROR NO: 96-01
KEYWORDS: POST1 SHELL NONLINEAR PDEF ETABLE PRNSOL PLNSOL
DESCRIPTION OF ERROR:
In POST1, for shell elements, (SHELL43, 91, 93, or 143) nonlinear
data (items SEPL,SRAT,HPRE,EPEQ,PSV,PLWK) are used (ETABLE, PDEF, NSEL,
NSORT commands) or displayed (PRNSOL,PLNSOL,PLESOL,*_/ GET commands) at
the top of shell location (SHELL,TOP) instead of the location specified
by the SHELL command.
FIRST INCORRECT VERSION(S):*_/ CORRECTED IN:*_/
Rev. 5.0 Rev. 5.3
SUGGESTED USER ACTION FOR RUNNING ON UNCORRECTED VERSION:
COMMENTS:
The PRESOL command will display both top and bottom shell data.

KEYWORDS: THERMAL ANALYSIS KZZ ORTHOTROPIC MATERIAL MATRIX
REUSE
DESCRIPTION OF ERROR:
For PLANE75,78, and SOLID5,70,87,90,98,122,123, when the
conductivities in the x and y directions (KXX and KYY) are not changed,
but the conductivity in the z direction is changed between substeps, the
results will be incorrect after the first substep. Conductivities may
change by being temperature-dependent.
FIRST INCORRECT VERSION(S):*_/ CORRECTED IN:*_/
Rev. 5.0 Rev. 5.3
ANSYS/Thermal Rev. 5.0A ANSYS/Thermal Rev. 5.3
SUGGESTED USER ACTION FOR RUNNING ON UNCORRECTED VERSION:
If KZZ does change, make sure that KXX has a slight change also.

ANSYS(Registered Trademark) CLASS3 ERROR REPORT
ERROR NO: 96-03
KEYWORDS: MATERIAL PROPERTIES BEAM ELEMENTS PIPE ELEMENTS
DESCRIPTION OF ERROR:
The results are incorrect for certain line elements after the first
substep when certain material properties (MP commands) change between
substeps (such as caused by a temperature-dependent material property)
and large deflections are not used (NLGEOM,OFF). The following specific
cases are erroneous:
1. BEAM3,4,23,24,44,54 and PIPE16,59, if the shear modulus (GXY) is
changed but Young's modulus (EX) is not changed.
2. PIPE17, the piping tee element, if any material property is changed.
FIRST INCORRECT VERSION(S):*_/ CORRECTED IN:*_/
Rev. 5.0 Rev. 5.3
ANSYS/LinearPlus Rev. 5.0A ANSYS/LinearPlus Rev. 5.3
SUGGESTED USER ACTION FOR RUNNING ON UNCORRECTED VERSION:
Use large deflections (NLGEOM,ON), even if it is not otherwise
needed. For item 1, one can also make a small change in EX when there is
a change in GXY.

ANSYS QA NOTICE
NOTICE NO: QA96-01
SUBJECT: POST1 NFORCE AXISYMMETRIC STRUCTURES
DESCRIPTION:
The NFORCE command has no specialization for axisymmetric
structures. Therefore, the POST1 NFORCE command produces incorrect
results for some loads when using axisymmetric structures. The NFORCE
command treats all forces and moments as if they were in three-
dimensional space.
There will be a change in the documentation to clarify this
limitation.
