DESCRIPTION:

                     Generate N point in GTMODELER,

     Problem may result in wrong answer or job aborts when more than 20
points are generated along a line using the GEN PT, NPTL menu in
GTModeler.  The model will be distorted if one tries to redraw the
screen.

Workaround:
     There is no workaround for this problem.  The problem will not occur
if less than 20 points are generated.

Dear Class3 Error Recipient:

     Enclosed you will find ANSYS Class3 Error Reports 95-30, 95-31, 95-
32, 95-33, 95-34, 95-35, and 95-36 as well as 95-07 R1.

     Class3 Error Report 95-07 R1 has been re-issued to include a
workaround.

     Also included in this mailing are two ANSYS QA Notices, QA95-05 and
QA95-06.  QA95-05 discusses implications of an ANSYS-imposed binary file
size limit.  QA95-06 provides clarification on display of large
deflection analysis results in POST1.

                                        Sincerely,

                                        ANSYS, Inc.

                                        Prashant Ambe

                  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:

                                 5.0A-10
               major revision level     special version identifier

               minor revision level     correction level

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 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.

     PCTHERMAL  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

DESCRIPTION OF ERROR:

     The LCSYS and RADTOL fields of the TORQC2D command macro are
reversed when using the TORQC2D dialog box in the Graphical User
Interface (GUI).  This could cause incorrect calculation of the torque.
The dialog box for the TORQC2D command macro is found in the following
menu path: Main Menu - General Postproc - Magnetic Calcs - Circular
Torque.

DESCRIPTION OF ERROR:

     For commands that permit specifying an entity number range with an
increment (e.g. NODE, NEND, NINC), if a negative value is used for the
increment then the command will not operate on the correct entity
numbers.  This can result in various items being incorrect (see comment).

DESCRIPTION OF ERROR:

     In POST1, the coordinate system for printout or display of results
(RSYS) will not be correctly used if:

     1.   The RSYS command specifies a user-defined coordinate system
          (reference number greater than 10):

and  2.   The user-defined system is subsequently re-defined (LOCAL, CS,
          CLOCAL, CSKP, etc.);

and  3.   The RSYS command is reissued to specify the re-defined system.

SUGGESTED USER ACTION FOR RUNNING ON UNCORRECTED VERSION:

     Use a different coordinate system reference number redefining the

specify a different coordinate system (e.g. RSYS.0) before reissuing the
RSYS command to specify the redefined system.

COMMENTS:

DESCRIPTION OF ERROR:

case was defined and active.

SUGGESTED USER ACTION FOR RUNNING ON UNCORRECTED VERSION:

     Select the proper constraint case via the "Sel Cons Case" item under

COMMENTS:

     The ANSYS/ProFEA User's Guide states that a thermal/stress analysis
will solve only the first constraint case and ignore the remaining cases.
However, if more than one constraint case was defined and active
(default), the ANSYS solver will use a combination of all thermal
constraint cases and the last structural case.

KEYWORDS:      PCG SOLVER     LARGE STRAIN        CONSTRAINT EQUATIONS

DESCRIPTION OF ERROR:

     If the PCG solver (EQSLV,PCG) is used with constraint equations in a
nonlinear analysis (Newton-Raphson or modified Newton Raphson), the
constant term of the constraint equation (CE command) changes with the
load step numbers, giving incorrect results.

KEYWORDS:      PRO/ENGINEER    THERMAL STRESS     REFERENCE TEMPERATURE

DESCRIPTION OF ERROR:

     Results from any thermal-stress solution run from within the ANSYS-

SUGGESTED USER ACTION FOR RUNNING ON UNCORRECTED VERSION:

     The following two steps should be done:

     1.   Select the proper constraint case via the "Sel Cons Case" item
          under the "Run Study" menu (required only if more than 1
          constraint case was defined).

and  2.   Include the proper Reference Temperature via the "Use .inp
          File" item under the "Run Study" menu using the following
          sequence of commands (temp should be the numerical value of the
          required Reference Temperature):
                    /SOLU
                    TREF, temp
                    SOLVE
                    FINISH

COMMENTS:

     The thermal expansion reference temperature may be specified in the
Pro/ENGINEER material file.  However, this value is not included in the
list of material properties given to the ANSYS program unless a
structural temperature is defined in Pro/MESH.

SUBJECT:  POST1     RSYS      LARGE DEFLECTION    PRNSOL    PRESOL


DESCRIPTION:

     In POST1, for a large deflection analysis (NLGEOM,ON) the element
stress and strain results displayed by the PRNSOL and PRESOL commands
should state that rigid body rotations are included when rotation of the
data is requested (RSYS).  Instead the output header implies that the
stress-strain results are in the requested coordinate system.

     Note that this is documented correctly in the Procedures Manual
(section 11.2.3); only the output header is incorrect when these
quantities are listed.

SUBJECT:       SYSTEM         FILES     SIZE LIMIT

DESCRIPTION:

     There is an ANSYS-imposed 8 gigabyte limit for the total size of an
ANSYS binary file.  The limit is applicable to all files, but most likely
will be encountered on the .tri files.  This affects:

     A.   all computers which use 32 bit integers (this includes all
          computers which run ANSYS except those from Cray Computers)

or   B.   all computers when the files are specified as type external
          (default).

WORKAROUND:

     Use the PCG or JCG solver if possible (which do not use a .tri
file), or run on the Cray with the binary files specified as type
internal (/FTYPE,,INT).

COMMENTS:

     Because most computers have a file size limit of 2 gigabytes, the 8
gigabyte ANSYS-imposed limit can usually be achieved only by using file
splitting on a .tri file (beta feature at Revisions 5.0A and 5.1).  In
this case, the 8 gigabyte limit applies to the total size of the
individual .tri file pieces.
