ANSYS [Registered Trademark] CLASS3 ERROR REPORT ERROR NO: 96-48 KEYWORDS: LSDYNA EDLOAD DESCRIPTION OF ERROR: The EDLOAD command erroneously transfers rotational degrees of freedom (Lab=ROTX, ROTY or ROTZ) nodal loads as rotational velocity degrees of freedom nodal loads (Lab=OMGX, OMGY or OMGZ).

ANSYS [Registered Trademark] CLASS3 ERROR REPORT ERROR NO: 96-49 KEYWORDS: LSDYNA ROTATED NODES DESCRIPTION OF ERROR: ANSYS/LS-DYNA ignores nodal rotations. Because rotated nodes are not properly error trapped for all cases, some items (such as displacement constraints) may be erroneously-interpreted in Global Cartesian coordinates rather than the rotated nodal coordinates. Note that the application of symmetry or anti-symmetry boundary conditions (DSYM,DL,DA) will automatically produce nodal rotations. Typical GUI Path(s): Main Menu>Preprocessor>Create>Nodes>To Active CS Main Menu>Preprocessor>Move/Modify>To Active CS Main Menu>Preprocessor>Loads>Apply>Displacement FIRST INCORRECT VERSION(S):*_/ CORRECTED IN:*_/ Release 5.3 Release 5.4 SUGGESTED USER ACTION FOR RUNNING ON UNCORRECTED VERSION: Apply all boundary conditions in the Global Cartesian coordinate system. Ensure that there are no non-zero nodal rotations in the model. This can be accomplished by issuing the following sets of commands. For each case, NLIST should list no nodes. NSEL.ALL $NSEL.U,ANG.XY,0.0 $NLIST,ALL NSEL.ALL $NSEL.U,ANG.YZ,0.0 $NLIST.ALL NSEL.ALL $NSEL.U.ANG,ZX.0.0 $NLIST.ALL COMMENTS: Error trapping will be expanded at Release 5.4 to prevent any use of rotated nodes in ANSYS/LS-DYNA.

ANSYS [Registered Trademark] CLASS3 ERROR REPORT ERROR NO: 96-50 KEYWORDS: SOLID92 PLANE2 SOLID87 CURVED EDGES DESCRIPTION OF ERROR: SOLID92 and PLANE2 may produce erroneous high stress concentrations for elements with curved edges that have lengths of the order of 1.0E-3 and less. SOLID87 may produce erroneous high fluxes across element faces whose edges are curved and have lengths of the order of 1.0E-3 and less. Typical GUI Path(s): There are numerous GUI paths that produce curved edge elements described above. FIRST INCORRECT VERSION(S):*_/ CORRECTED IN:*_/ Release 5.3 Release 5.4 Component Products Release 5.3 Component Products Release 5.4 SUGGESTED USER ACTION FOR RUNNING ON UNCORRECTED VERSION: Set the undocumented KEYOPT(8) for SOLID92, PLANE2, SOLID87 equal to 1 and run the problem. This will produce the correct stresses and fluxes. COMMENTS: AUTHOR/CORRECTOR: DATE: December 6, 1996 Pakal Rahulkumar REVIEWED BY QA: DATE: December 6, 1996 William J.

ANSYS [Registered Trademark] CLASS3 ERROR REPORT ERROR NO: 96-51 KEYWORDS: /GRAPHICS.POWER POST1 LCOPER PLNSOL DESCRIPTION OF ERROR: The POST1 element results displayed by the PLNSOL command will be incorrect if all of the following commands have been issued: 1. Power graphics are enabled (/GRAPHICS, POWER) 2. Element results are displayed by the PLNSOL command 3. Then load case operations are performed (LCOPER) 4. Then the operated element results are displayed by the PLNSOL command. The second and subsequent PLNSOL command will display the same results as the first PLNSOL command until a PLESOL command is issued.

ANSYS [Registered Trademark] CLASS3 ERROR REPORT ERROR NO: 96-52 KEYWORDS: DOCUMENTATION SELECT DESCRIPTION OF ERROR: The Commands Manual documentation for the select commands (xSEL family of commands, where x is A, K, L, V, E or N) fails to describe a tolerance that is used when unequal MIN and MAX values are entered to indicate a select range. For such cases, a tolerance of +/- 1E-8*_/(MAX - MIN) is added to the select range. Users should be aware that using exceptionally large values for MIN and/or MAX may cause unanticipated items to be chosen by the select due to this tolerance. This typically occurs when selecting all positive (or negative) values by entering an exceptionally large value in the MAX (or MIN) field to denote infinity. Typical GUI Path(s): Utility Menu>Select>Entities FIRST INCORRECT VERSION(S):*_/ CORRECTED IN:*_/ Release 5.3 Commands Manual Release 5.4 Commands Manual SUGGESTED USER ACTION FOR RUNNING ON UNCORRECTED VERSION: When selecting, use a value for MAX and/or MIN that is reasonable for the select range that is desired. COMMENTS: Note that this tolerance was introduced at Release 5.3 and any previous inputs may show this incompatibility.

ANSYS [Registered Trademark] CLASS3 ERROR REPORT ERROR NO: 96-53 KEYWORDS: PIPE20 ELEM20 STRESS STIFFENING ANTYPE, BUCKLE SSTIF, ON PSTRESS, ON DESCRIPTION OF ERROR: The axial force used for the stress stiffening matrix of PIPE20 (the plastic straight pipe element) does not include the effect of internal or external pressure. Stress stiffening is activated by the SSTIF, ON or PSTRES, ON commands. TYPICAL GUI PATH(S): SSTIF,ON and PSTRESS,ON - Main Menu>Preprocessor>Loads>Analysis Options Main Menu>Solution>Analysis Options FIRST INCORRECT VERSION(S):*_/ CORRECTED IN:*_/ Rev. 3.0 Release 5.4 SUGGESTED USER ACTION FOR RUNNING ON UNCORRECTED VERSION: Consider using PIPE16, the elastic straight pipe element. COMMENTS: The commands noted above which activate stress stiffening apply to Revision 5.0 and up. Earlier releases used different commands to activate stress stiffening.

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 component 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 the full ANSYS product, for starting at Rev. 5.0, and beyond, unless otherwise noted. PREPPOST contains relevant errors the full ANSYS product, for shown for included pre- and postprocessing functionality ANSYS Component Products is an All component products that inclusive term for were issued at the stated revision level(s) PC/LINEAR is equivalent to WS/LINEAR at Rev. 4.4A. and ANSYS/LinearPlus starting at Rev. 5.0A. PC/THERMAL is equivalent to WS/THERMAL at Rev. 4.4A, and ANSYS/THERMAL starting at Rev. 5.0A. PC/MAGNETIC is equivalent to ANSYS/Emag starting at Rev. 5.0A ANSYS [Registered Trademark] January 8, 1997 Dear Class3 Error Recipient: Enclosed you will find ANSYS Class3 Error Reports 96-47, 96-48, 96-49, 96-50, 96-51, 96-52, and 96-53.
