Therefore, solution sequences (SOLs 105 and 200; SOLs 103 and 107 through 112 with STATSUB) that require differential stiffness to get correct result, give wrong results. However, for the nonlinear solution sequences (SOLs 106, 129, and 400), the differential stiffness is not required to give correct results, therefore, the results are correct, if the solution converges. 1-19459484 2007.0.0 ( Documentation/QRG - PCOMP - Remark 11 obsolete, kdiff is now calculated for unsym layup Remark 11 under the PCOMP Quick Reference Guide description that indiates that it is not recommended to use an unsymmetric layup in solutions that require differential stiffness is not longer applicable. 1-20748432 Elements - PBEAM entries with 2 identical stations yields incorrect mass properties PBEAM entries with two identical stations yields incorrect mass properties.

For example STRESS(BILIN) is requested and FORCE(CENTER) is requested. 1-46052930 Optimization/Design Sensitivity - MFREQ with RANDOM - UWM 2071 (DPD2) In SOL 200, with MFREQ and RANDOM, after the 1st design cycle the following message is issued.

The differences are attributed to a small difference in the way the transverse shear stiffness is calculated. . 1-50354037 Nonlinear Analysis - TETRA(10), STRAIN - Missing Output A request for STRAIN output for TETRA(10) elements in nonlinear solution 106, does not generate any strain output. STRESS output is generated instead. 1-50932651 Complex Eigenvalues - EIGC, CLAN - Wrong Answers Complex Lanczos produces roots for unsymmetric fluid-structure interaction problems (such as tpl/ac10704) which have a non-zero real part; however, when there is no damping, the roots should be pure imaginary. Avoidances include: 1) force the computations to be performed in complex arithmetic by specifying sys108=16384 2) use old single-vector Lanczos by specifying sys108=2 3) use SOL 110 in place of SOL 107, and use HESS for the complex eigensolution. 1-51120736 Matrix Methods - Insufficient core for FBSMEM; sfm 7340 (LNNRIGL) - unknown internal error Defining FBSMEM/system(146) to a large value, for example 100, can lead to the following messages: INSUFFICIENT CORE FOR FBSMEM IN REIGL INCREASE MEMORY BY AT LEAST 1111366876 WORDS *** SYSTEM FATAL MESSAGE 7340 (LNNRIGL) UNKNOWN INTERNAL ERROR OCCURRED. The problem is that Nastran does not stop at this point. Instead Nastran proceeds with MMFIND1 and thereafter tries to find a solution again. But the same error happens again and a solution cannot be found (ufm 4405). Avoidance: Increase memory. 1-51434272 Documentation/QRG - SMETHOD, ITER - UFM 9058, Wrong Answers The iterative solver methods do not work in the presence of SUPORTi entry, this is documented in a remark under the ITER bulk data entry. It should be noted that param, inrel uses the SUPORT entry and therefore the iterative solver may not be used with this parameter. If attempted either the message: USER FATAL MESSAGE 9058 (SUPER3) THE SOLUTION FOR THE RESIDUAL STRUCTURE DOES NOT EXIST. or incorrect results will occur. 1-51517141 Documentation/QRG - PSOLID - TETRA(5-10 node) supported in SOL 106, 129 and 400 In Table 8-43 at the end of the PSOLID description in the Quick Reference Guide it incorrectly indicates that the TETRA 5-10 is not supported in SOL 106, 129 and 400. 1-51861461 Restarts/External Superelements - EXTSEOUT(DMIGPCH) - Wrong Answers A SOL 111 restart from a previous sol 111 job which contains an external SE created with EXTSEOUT(DMIGPCH) produces incorrect results when K2GG and M2GG have been omitted in the restart. The results are the same as for the cold start. This happens because KAA is available from the restart database. 1-52101228 Documentation/DMAP Programmer's Guide - OUTPUT4 Record. There is an error in the DMAP Programmer's Guide documentation of the OUTPUT4 record. In ASCII mode, word 3 in record 2 of each matrix is the number of TERMS in the column, not the number of WORDS. In the binary format, word 3 of record 2 is, in fact, the numbr of words in the column. The TERMS and WORDS values are the same for RS and CS matrices, the TERMS value is WORDS/2 for RD and CD matrices. The documentation of the OUTPUT4 file format in the DMAP Module Programmer's Guide must be corrected. Note that the format of the ASCII OUTPUT4 file (at least in this regard) has not changed since Version 65. 1-52240428 2007.0.2 External Superelements - SOL600,101 - UFM 316 (IFPDRV) DMIG SOL 600 with external superelements will fail with the message: *** USER FATAL MESSAGE 316 (IFPDRV) ILLEGAL DATA ON BULK DATA ENTRY DMIG DMIG *KAAX 5 1 +000001 *+000001 5 1 2.347553830D+05 +000002 1-52721371 DMP/Frequency Response - DOMAINSOLVER, PARAM,LFREQ - UFM 3047 (GKAM) Use of PARAM,LFREQ in a DMP modal frequency response analysis may result in the fatal message: *** USER FATAL MESSAGE 3047 (GKAM) NO MODES HAVE BEEN SELECTED FOR USE IN THE ANALYSIS.
