ANSYS [Registered Trademark] ANSYS, Inc. 201 Johnson Road Telephone 412.746.3304 Houston, PA 15342-1300 Facsimile 412.746.9494 September 27, 1995 Dear Class3 Error Recipient: Attached you will find ANSYS Class3 Error Reports 95-52, 95-531, 95-54 and 95-55. For your convenience, also enclosed with this mailing are ANSYS Class3 Error Summary Reports for Rev. 5.0A and Rev. 5.1, sorted both by keyword and by error report number. Sincerely ANSYS, Inc. William J. Bryan Quality Assurance Manager Attachment 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 "5.0A-10" 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 pan 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 shown for the full ANSYS product for included pre- and postprocessing functionality ANSYS [Registered Trademark] CLASS3 ERROR REPORT ERROR NO: 95-52 KEYWORDS: MESH MIDSIDE NODES DESCRIPTION OF ERROR: 1. Using an all-quadrilateral mapped mesh of a 3-sided surface (AMESH; ESHAPE,2) using a midside-noded element type (such as SHELL93) may not follow the out-of-plane curvature of the area for the mid-node placement, but instead may place the mid-nodes linearly between their neighboring corner nodes. 2. Brick element mapped meshes bounded by any 3-sided surface (VMESH; ESHAPE,2) using midside-noded element types (such as SOLID95) may not follow the out-of-plane curvature of the bounding area for mid-node placement, but instead may place the mid-nodes linearly between their neighboring corner nodes. FIRST INCORRECT VERSION(S):**_/ CORRECTED IN:*_/ Rev. 5.1 Rev. 5.2 SUGGESTED USER ACTION FOR RUNNING ON UNCORRECTED VERSION: Issue MODMSH, NOCHECK, then modify midside nodes as required to place them on the surface (NMODIFY). COMMENTS: Analysis results from elements not conforming to a curved surface are frequently less accurate than results from elements following such curvature. AUTHOR/CORRECTOR: DATE: September 26, 1995 Scott Canann REVIEWED BY QA: DATE: September 26, 1995 William J. Bryan APPROVAL: DATE: September 26, 1995 John A. Swanson *_/ If a product name is not included in the "first incorrect version", the full ANSYS program is implied. 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. Manual corrections are included in on-line documentation as appropriate. Please see the reverse side of this sheet for additional information on ANSYS revision identifiers. FORM QA25 DEC 19, 1988 ANSYS [Registered Trademark] CLASS3 ERROR REPORT ERROR NO: 95-53 KEYWORDS: CORROSION THICKNESS ALLOWANCE ELEM16 ELEM17 ELEM18 DESCRIPTION OF ERROR: When a non-zero corrosion thickness allowance is specified (real constant TKCORR), all stresses and strains are incorrect for PIPE16, PIPE17, and PIPE18. The correct magnitude of the stresses is either equal to or less than the reported magnitude of the stresses. FIRST INCORRECT VERSION(S):*_/ CORRECTED IN:*_/ Rev. 5.0 Rev. 5.2 ANSYS/Linear Plus Rev. 5.0A ANSYS/Linear Plus Rev. 5.2 SUGGESTED USER ACTION FOR RUNNING ON UNCORRECTED VERSION: COMMENTS: AUTHOR/CORRECTOR: DATE: September 26, 1995 Lisa Fordanich REVIEWED BY QA: DATE: September 26, 1995 William J.

FORM QA25 DEC 19, 1988 ANSYS [Registered Trademark] CLASS3 ERROR REPORT ERROR NO: 95-54 KEYWORDS: APDL ARFACE GET FUNCTION DESCRIPTION OF ERROR: When the ARFACE(E) "get function" is used to get the area of element faces, a value of zero is returned for the following elements: SOLID5, PLANE13, FLUID29, FLUID30, PLANE53, SOLID62, SOLID96, SOLID97, SOLID98, INFIN110, INFIN111, PLANE121, SOLID122, SOLID123. FIRST INCORRECT VERSION(S):*_/ CORRECTED IN:*_/ Rev. 5.1 Rev. 5.2 ANSYS/FLOTRAN Rev. 5.1 ANSYS/FLOTRAN Rev. 5.2 SUGGESTED USER ACTION FOR RUNNING ON UNCORRECTED VERSION: Switch element type to an appropriate element type that has a pressure or convection face before using ARFACE get function; then switch back to the original element type. COMMENTS: The error occurs because the above elements do not have pressure or convection characteristics. The ARFACE get function returns the correct value for elements that do have p on characteristics. AUTHOR/CORRECTOR: DATE: September 26, 1995 Christopher W. Aiken REVIEWED BY QA: DATE: September 26, 1995 William J. Bryan APPROVAL: DATE: September 26, 1995 John A.

FORM QA25 DEC 19, 1988 ANSYS [Registered Trademark] CLASS3 ERROR REPORT ERROR NO: 95-55 KEYWORDS: POST1 ESEL MULTIPLE SOLUTIONS DESCRIPTION OF ERROR: POST1 results will be incorrect if the solution being post-processed was performed on a subset (ESEL) of a model that as previously solved using a different selected set of elements, and all of the following are true: 1. ANSYS was not exited ( /EXIT) between solutions or the resumed database contained the model solution data (/EXIT.SOLU or /EXIT.ALL). and 2. Any of the elements unselected for the solution are reselected in POST1. FIRST INCORRECT VERSION(S): *_/ CORRECTED IN: *_/ Rev. 5.0 Rev. 5.3 Component Products Rev. 5.0A Component Products Rev. 5.3 SUGGESTED USER ACTION FOR RUNNING ON UNCORRECTED VERSION: Do not reselect any of the elements unselected for the solution or remove the earlier solution from the database ( /EXIT or SAVE). COMMENTS: The error occurs because the results of the previous solution for the unselected elements still reside in the database. AUTHOR/CORRECTOR: DATE: September 26, 1995 David L.
