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".



                                        Sincerely,

                                        

                                        ANSYS, Inc.

                  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

     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.
