Very truly yours, Sandra J. Andrews Nuclear Administrator G-1151 M/S 7A-33 (206) 865-6248 Attachment(s): ANSYS Class3 Error Reports 96-12, 96-13, 96-14 and 96-02 R1 ANSYS [Registered Trademark] ANSYS, Inc. 201 Johnson Road Telephone Houston, PA 15342-1300 412.746.3304 Facsimile 412.746.9494 April 2, 1996 Dear Class3 Error Recipient: Attached you will find ANSYS Class3 Error Reports 96-12, 96-13, 96- 14 and 96-02 R1. ANSYS Class3 Error Report 96-02 is being reissued to add element PLANE121 and further clarify the error description for elements SOLID122 and 123. Sincerely, ANSYS, Inc. William J. Bryan Quality Assurance Manager 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 "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 orange 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. 43A 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 guarrantee 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 function- ality ANSYS [Registered Trademark] CLASS3 ERROR REPORT 96-12 KEYWORDS: SOLID97 SOLID62 ELEM97 ELEM62 RESISTIVITY ESYS DESCRIPTION OF ERROR: For SOLID97 and SOLID62, the global Cartesian coordinate system is always used for the resistivity material property. If an element coordinate system for resistivity is requested by the ESYS command, it is ignored. FIRST INCORRECT VERSION(S):*_/ CORRECTED IN:*_/ Rev. 5.2 Release 5.3 ANSYS/Emag Rev. 5.2 ANSYS/Emag Release 5.3 SUGGESTED USER ACTION FOR RUNNING ON UNCORRECTED VERSION: COMMENTS: AUTHOR/CORRECTOR: DATE: April 1, 1996 Jian-She Wang REVIEWED BY QA: DATE: April 1, 1996 William J. Bryan APPROVAL: DATE: April 1, 1996 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. ANSYS [Registered Trademark] CLASS3 ERROR REPORT ERROR NO. 96-13 KEYWORDS: SUBSTRUCTURES TOTAL COMMAND DESCRIPTION OF ERROR: During a substructure generation run (ANTYPE,SUBSTR), nodal forces applied to master degrees of freedom that are selected with the TOTAL command erroneously have their effect doubled. FIRST INCORRECT VERSION(S):*_/ CORRECTED IN:*_/ Rev. 4.0 Release 5.3 SUGGESTED USER ACTION FOR RUNNING ON UNCORRECTED VERSION: Specify master degrees of freedom with the M command on all degrees of freedom that have applied nodal forces rather than using the TOTAL command.

ANSYS [Registered Trademark] CLASS3 ERROR REPORT ERROR NO: 96-14 KEYWORDS: SHELL63 ELEM63 THERMAL LOAD NEWTON-RAPHSON DESCRIPTION OF ERROR: When SHELL63, the elastic she]] element is used with: 1. non-uniform thermal loads (applied with the BF or BFE commands) that induce membrane (in-plane) deformation; and 2. any nonlinearity in the model and 3. extra displacement shapes (applied with KEYOPT(3)=0 [default] or 2); all results are inaccurate. A nonlinearity exists if a nonlinear geometric or material option is chosen, if an element type which is inherently nonlinear is present, or if nonlinearity is explicitly requested with the NROPT command. FIRST INCORRECT VERSION(S):*_/ CORRECTED IN:*_/ Rev. 5.0 Release 5.3 SUGGESTED USER ACTION FOR RUNNING ON UNCORRECTED VERSION: COMMENTS: For most analyses, the effect of this error is negligible. Non- uniform thermal loads that induce bending deformation are treated correctly. AUTHOR/CORRECTOR: DATE: April 1, 1996 Peter Kohnke REVIEWED BY QA: DATE: April 1, 1996 William J.

ANSYS [Registered Trademark] CLASS3 ERROR REPORT ERROR NO: 96-02 R1 KEYWORDS: ORTHOTROPIC MATERIAL MATRIX REUSE DESCRIPTION OF ERROR: COMMENTS: [Redline: All results will be incorrect after the first substep, when orthotropic properties change between substeps because the conductivity matrices are erroneously reused for the following cases:] [Redline: A. 1. aPLANE121, or SOLID122,123 (electrostatic solid) element is used; and 2. orthotropic permittivity is used (using the PERY and/or PERZ material properties); and 3. only the X-direction permittivity (material property PERX) changes: or B. 1. aPLANE75,78 or SOLID70,87,90 (thermal solid) or a SOLID 5,98 (coupled-field solid) element is used; and 2. orthotropic permittivity is used (using the KYY and/or KZZ material properties); and 3. only the Z-direction conductivity (material property KZZ) changes.] [Redline: Material properties may change between substeps by being temperature-dependent, or by being redefined.] FIRST INCORRECT VERSION(S):*_/ CORRECTED IN:*_/ Rev. 5.0 Release 5.3 ANSYS Thermal Rev. 5.0A ANSYS/Thermal Release 5.3 SUGGESTED USER ACTION FOR RUNNING ON UNCORRECTED VERSION: [Redline: In either of the above cases, make sure that the material properties in all directions also have at least a very small change.] COMMENTS: AUTHOR/CORRECTOR: DATE: April 1, 1996 Peter Kohnke REVIEWED BY QA: DATE: April 1, 1996 William J.
