1-19390023 Documentation/QRG - CQUAD4 differential stiffness remark obsolete
Remark 6 for CQUAD4 should now read:
...\sequences with geometric nonlinear
analysis (SOL 106, 129, 153, 159 with PARAM LGDISP>0) The differential stiffness is computed correctly in
V2004 and higher (SOLs 5, 16, 105 and 200 and SOL 106 with PARAM LGDISP <=0)
1-19689679 2007.1.0 Case Control - Scale Factor applied to P2G lead to UFM 300
Attempting to apply a scale fact to P2G, (i.e. P2G = 1.25*PAX) may lead to user
fatal message 300 in the case control section or the factors may be ignored.
1-19948040 Elements - PSHEAR with MAT1 and Nu=-1 gives traceback
If a PSHEAR entry references a MAT1 entry with a value nu=-1, the job will fail
with a traceback since formulation of the element contains the term (1+nu).
1-21553341 2007.1.0 Elements - CBEND, TEMP(INIT) - SFM 4276 with the traceback at SDR2
A model with a CBEND element that only defines the Initial Temperature for the
thermal load failed with SFM 4276 in the SDR2 module followed by a traceback.
Avoidance: Add TEMP(LOAD) command in the case control.
See attachment for the model.

1-22716666 2007.0.0 Installation - Windows Only, symbol=LM_NO_SNMP=1 missing from nast20051.rcf
The symbol=LM_NO_SNMP=1 missing from the nast20051.rcf. This may cause
problems with the flexlm licensing on older Windows operating systems.
1-23956243 2007.1.0 Fastener Elements - CFAST *** USER FATAL MESSAGE 7635 (MDG2ED)
Models with CFAST elements may fail inexplicably with the following message:

FOR CFAST ELEMENT ID= 177459, WITH FORM=ELEM OR PROP , THE SPOT WELD
AREA LIES OUTSIDE THE DEFINED SHELL SURFACE.
USER INFORMATION: THE NUMBER OF PAIRS OF CONNECTING SHELL ELEMENTS IS 0
BUT 4 PAIRS ARE REQUIRED.

Avoidance: There is no avoidance.
1-24287255 2007.0.1 Documentation/QRG - PARAM OMID is not supported in SOL 106
Parameter OMID is not supported in SOL 106 as indicated in Table 5-1 of the
PARAM section
1-24374298 Superelements - SEBULK EXTOP4 - UFM 4156 SEMA
If the KAA matrix in OP4 format is not Gsize (i.e. GRIDs on EXTERN <> 123456)
then the following error will occur during the assembly run:
*** USER FATAL MESSAGE 4156 (SEMA)

Avoidance: User must merge the matrix to Gsize with dmap.
This error is fixed in MSC.Nastran 2005.5.1 and MD Nastran 2006.0.1

The CBUSH1D element causes SOL 600 to fail without any messages.
1-36316035 2007.0.0 Documentation/QRG - CQUAD4, CTRIA3 - Offsets, ZOFF
Remark 6 of the QRG CQUAD4 and CTRIA3 description is in error. For CQUAD4 and
CTRIA3 with offset (due to ZOFFS and/or unsymmetric plies and/or z0 defined on PCOMP or PCOMPG) the differential stiffness is incorrect. Hence solutions with
the need for differential stiffness (dynamic analysis with prestress, linear and nonlinear buckling) will produce incorrect results. However solutions with
nonlinear geometric behavior (param,lgdisp,1) will produce correct results when
the solution has converged. Please note that QUADR and TRIAR with offset will
give incorrect results in any case.
1-37202949 Documentation/QRG - MCFRACTION - UWM 300
A request of MCFRACTION output for a SET that contains no degrees of freedom in
the analysis set, will result in the message:
*** SYSTEM WARNING MESSAGE 3001 (MCFRAC)
THE INPUT DATA BLOCK NAMED RPHMCS AT POSITION 5 DOES NOT EXIST.
For example:
SET 98765 = 61/t1 SET 88765 = 0.1,0.2 $
mcfraction(structure,print,punch,solution=88765, sort=absd,key=fraction,filter=0.0,null=12, items=(fraction,scaled)) = 98765
where t1 of grid 61 is constrained in the s-set will result UWM 300.
1-37426759 2007.0.0 Parallel Processing/Frequency Response - Poor DMP Performance with multiple load cases For any SOL 111 modal frequency response analysis with multiple load cases, DMP
performance will suffer during MPI communication of the dynamic load matrix.
Avoidance: apply the following DMAP alter:
compile freqrs
alter 'DISUTIL ppfe', '' $ type parm,,i,n,iproc $ iproc=2 $
do while ( iproc<=nproc ) $
disutil ppfe,,,/ppftmp/iproc/-1/10 $ send to master if ( procid=1 ) then $ add ppfe,ppftmp/ppfx $ if ( iproc=nproc ) then $ equivx ppfx/ppf0/-1 $ else $
equivx ppfx/ppfe/-1 $ endif $
delete /ppftmp,ppfx,,, $ avoid ufm 1126 endif $
iproc = iproc + 1 $ enddo endalter

1-40643851 2007.0.1 SOL 700 - Initial velocity is incorrect if analysis coordinate is defined in GRID
If analysis coordinate of GRID is defined using a local coordinate which is
based on another local coordinate, the initial velocity is incorrect in SOL 700.
