QA Notice QA96-04 is being issued to clarify a warning message produced when the LDREAD command is used to transfer heat generation rates from a harmonic magnetic analysis to a FLOTRAN analysis. As mentioned in the QA Notice, a macro is available on the ANSYS HomePage that may be used to assist users in transferring heat generation rates for such cases. Also enclosed, for your convenience, are Class3 Error Report Summaries for Rev. 5.1 and Rev. 5.2, sorted both by keyword and Class3 Error Report Number. Sincerely, ANSYS, Inc. Ken Podlaszewski Associate QA Engineer ANSYS is a registered trademark of SAS IP 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 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 errors the full ANSYS product, shown for for included pre- and postprocessing functionality ANSYS[Registered Trademark] CLASS3 ERROR REPORT ERROR NO: 96-15 KEYWORDS: GP LSWRITE LSSOLVE DESCRIPTION OF ERROR: Use of a file created by the LSWRITE command, when used in combination with gaps defined by the GP command, can lead to doubling of the gap stiffness on the first load step if the LSWRITE command was issued after the gaps were defined and the load step file (LSSOLVE) is read without deleting the gaps in the database (using GPDELE). FIRST INCORRECT VERSION(S):*_/ CORRECTED IN:*_/ Rev. 5.0 Release 5.3 ANSYS/LinearPlus Rev. 5.0A ANSYS/LinearPlus Rev. 5.3 SUGGESTED USER ACTION FOR RUNNING ON UNCORRECTED VERSION: 1. Issue LSWRITE before defining gaps; or 2. SAVE the database before defining the gaps and RESUME the database after defining the gaps and issuing the LSWRITE command; or 3. Delete the gaps after issuing the LSWRITE command and SAVE the database. COMMENTS: 1. The doubling of the gaps occurs only on the first load step, because after the first load changes in the gap stiffness are not allowed. 2. In Release 5.3, a warning will be issued when gaps are read in from an input file for a model in which gaps already exist. The definition will not be blocked, however, since under some conditions it may be desirable to duplicate gaps at a node. 3. The procedure for running in the corrected version is the same as for running in the uncorrected version. AUTHOR/CORRECTOR: DATE: May 28, 1996 Christopher W. Aiken REVIEWED BY QA: William J.

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.

ANSYS[Registered Trademark] CLASS3 ERROR REPORT ERROR NO: 96-16 KEYWORDS: IMPOSED DEGREES OF FREEDOM RAMP TO ZERO DESCRIPTION OF ERROR: All results are incorrect when: 1. one or more imposed degrees of freedom (D command) are ramped over a load step (KBC,O) from a nonzero value to a zero value: and 2. there are at least two substeps in the ramp; and 3. option on the NROPT command is 1 (FULL) or 2 (MODI) (option defaults to this when using plasticity, large deflection, contact elements, etc.). FIRST INCORRECT VERSION(S):*_/ CORRECTED IN:*_/ Rev. 4.0 Release 5.3 ANSYS/Emag Rev. 5.0A ANSYS/Emag Release 5.3 SUGGESTED USER ACTION FOR RUNNING ON UNCORRECTED VERSION: Either ramp imposed degree(s) of freedom to a very small non-zero value (e.g. 1.0e-8) instead of zero, or use a value of 3 (INIT) for option on the NROPT command. COMMENTS: At Revisions 4.0 to 4.4, the NT command could also be used to specify imposed degrees of freedom.

ANSYS[Registered Trademark] CLASS3 ERROR REPORT ERROR NO: 96-17 KEYWORDS: MODAL ANALYSIS LARGE DEFLECTION DESCRIPTION OF ERROR: The stresses in modal and spectrum analyses of large deflection solutions (See section 3.3.4 of the Procedures Manual) are incorrect. FIRST INCORRECT VERSION(S):*_/ CORRECTED IN:*_/ Rev. 5.1 Release 5.3 SUGGESTED USER ACTION FOR RUNNING ON UNCORRECTED VERSION: COMMENTS: The frequencies and mode shapes in the uncorrected version are correct. The correction at Release 5.3 will require the use of a new command (UPCOORD, on) to update the coordinates of the elements upon which to base the stress calculations.

ANSYS[Registered Trademark] CLASS3 ERROR REPORT ERROR NO: 96-20 KEYWORDS: THERMAL CONVECTION DELETED FILM COEFFICIENT DESCRIPTION OF ERROR: In a thermal analysis, the conductivity matrix does not get updated to reflect the absence of a convection surface if 1. either A. NROPT.AUTO [default] is used and no thermal material properties are tempterature-dependent and no radiation is present; or B. IMPORTANT is used; and 2. the film coefficient of a convection surface is deleted in the second or later load step (by using either the SFDELE/SFABELE/SFEDELE/SFLDELE commands; or resetting the film coefficient to zero); This erroneous conductivity matrix will continue to be used (unless the film coefficient is again changed to a nonzero value), yielding incorrect results. FIRST INCORRECT VERSION(S):*_/ CORRECTED IN:*_/ Rev. 5.1 Release 5.3 ANSYS/THERMAL Rev. 5.2 ANSYS/THERMAL Release 5.3 SUGGESTED USER ACTION FOR RUNNING ON UNCORRECTED VERSION: Instead of totally removing the film coefficient, simply reduce it to a very small value. Alternatively, NROPT,MODI can be used. COMMENTS: Ramping of a film coefficient down to zero in one load step with a series of substeps is correctly handled.

ANSYS QA NOTICE NOTICE NO: QA96-04 SUBJECT: CFD FLUID FLOTRAN MAGNETIC HARMONIC COUPLED FIELD DESCRIPTION: If the LDREAD command is used to transfer heat generation rates from an ANSYS harmonic magnetic analysis to a FLOTRAN analysis, LDREAD fails to transfer the imaginary portion of the heat generation rate. Note - for such cases, the following warning message is produced: Invalid KIMG key ( 2 ) for load label HGEN, when using FLOTRAN elements Valid key is 0. The KIMG key is reset to 0. AFFECTED VERSION: Rev. 5.2 COMMENTS: The Macro flohgen.mac is available on the ANSYS HomePage (http://www.ansys.com) in the Customer Information Area. It may be used to correctly transfer heat generation loads from an ANSYS harmonic magnetic analysis to FLOTRAN.
