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

Dear Class3 Error Recipient:
Enclosed you will find ANSYS Class3 Error Reports 96-06, 96-07,
96-08, 96-09, 96-10, 96-11 and also ANSYS QA Notice QA96-03.
ANSYS, Inc. is now in the process of moving to a new database
management system for business operations. During this transition we
will be making Class3 Error Reports available to all customers. For
customers who have not purchased maintenance this is an example of one of
the services you could receive with the purchase of maintenance.
A customer area now exists on the ANSYS HomePage
(http://www.ansys.com). This customer area currently contains Class3
Error Reports, QA Notices and Class3 Error Report Summaries. To access
it, pick "Customer Information Area" on the ANSYS HomePage. The username
and password for accessing the Customer Information Area are as follows:
username: customer password: ain1fm
Note, to make it easy to remember, the password is an acronym "ANSYS is
number 1 for me".

ANSYS Revision Identifier Description
ANSYS revision identifiers consist of it 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 out 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 shown for the full ANSYS
product,
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/THERMAL is equivalent to WS/THERMAL at Rev.
4.4A,
and ANSYS/THERMAL
starting at
Rev. 5.0.
PREPPOST contains relevant the full ANSYS
errors shown for product, for
included pre- and
postprocessing
functionality

NOTICE NO: QA96-03
KEYWORDS: MASS LUMPM.ON ELEMENT23,24,29,30,44,54,59,63
DESCRIPTION:
Mass matrix lumping (accessed by LUMPM.ON), by its very nature,
suppresses mass coupling between degrees of freedom. Therefore the
following limitations and cautions exist.
A. Lumping should not be used for FLUID29 or FLUID30 elements. (It is
already not allowed for FLUID38 elements.)
B. Lumping should not be used for BEAM44 elements when using member
releases in the element UY or UZ directions.
C. Lumping should not be used for PIPE59 elements when using 'added
mass' on the outside of the pipe. In this case, the implied
coupling exists when the element x-axis is not parallel to one of
the three nodal axes.
D. Lumping should not be used for BEAM23, BEAM24, BEAM44, or BEAM54
elements when used with explicitly defined or implied offsets.
E. The effect of the implied mass offsets with warped SHELL63 elements
is not considered by the lumping logic.
Use LUMPM.OFF (default) for the above cases.
