Подскажите! Пытаюсь посчитать в NX6 в «Расширенной симуляции» элементарную деталь, а UG не хочет ее считать. Точнее процесс расчета начинается (разбивает сетку и т.п.), но результат не выдает!? У меня уже была такая проблема в NX4 из-за того что, то присутствовали русские названия в пути файла, то из-за того, что пытался по сети расчет сделать Но сейчас все делаю вроде нормально, а вот результата нет Помогите, если кто знает, в чем проблема?

MD Nastran/MSC.Nastran Complete Error List Current Update: Jan
14, 2011 ——————————————This section
includes a description of all known errors and general limitations
in all releases of MSC.Nastran and MD Nastran. The «version is the
version on the f06 title page». Recent versions are sometimes
referred to by the CD id as follows: MSC.Nastran 2005R3 = 2005.5.0
MSC.Nastran 2005R3b = 20005.5.2 MD Nastran R1 = 2006.0.0 MD Nastran

Nastran 2010.1.1 = 2010.1.1 MD_MSC Nastran 2010.1.3 = 2010.1.3 If
the Version = «GL» then this indicates a General Limitation which
indicates a fix is not planned. Continuous updates to the error

CR 868 STRESS(PUNCH) will not properly output the HEXA, PENTA,
BEND, BEAM, TRIA6, or QUAD8 elements. Element margins of safety
(ROD, CONROD, TUBE, and BAR elements) will produce poor punched
formats if stress allowables are not given on the referenced MATi
entries. CR 890 MSC / MD Nastran Grid Point Force — GPFDR — UFM
3008 The open core requirement for the GPFDR module can be as large
as (6 X BUFFSIZE + 14 X number of grids) if the grids use a
nonrectangular displacement coordinate system. For problems in
basic coordinates, the grid requirement drops to 8 X number of
grids. CR 1103 MSC / MD Nastran Dynamic Response — TRD, TRD1, FRRD,
FRR — UFM 3005 If the MGIV method of real eigenvalue extraction
computes modes for massless DOF with uncoupled stiffness terms, the
eigenvalue is large (1.E+35) as it should be, but the generalized
stiffness is 0.0 (it should also be 1.E+35). Null eigenvectors may
be produced. An avoidance is to use PARAM,HFREQ or PARAM,LMODES to
discard these bad modes in dynamics. CR 1357 MSC / MD Nastran
Aeroelastic Analysis — GI — Poor Accuracy The linear splines used
to connect structural and aerodynamic degrees of freedom are
sensitive to modeling techniques, particularly on short-word
machines. This included all machines except CRAY, CDC and NEC. It
is good practice to have the spline axis coincide with the
structural grid points, and to avoid discontinuities in the lines
joining structural grid points by using separate splines on each
side of the discontinuity. CR 1575

an OUTPUT(XYPLOT) command is in case control, but there are no
other XYPLOT commands, all printed output requests are ignored. An
avoidance is to put in XYPLOT requests or remove the OUTPUT(XYPLOT)

Answers When the MID4 option of the PSHELL card is used to simulate
offset of the element centerline from the grid point plane, the
element is somewhat too stiff. The error increases with the ratio

MSC / MD Nastran DMAP — DIAG 4 — Addressing ERROR If DIAG 4 is used
on restart, the program may exit abnormally at the start of the
run. The DIAG 4 cross reference output for Label Names will be
incorrect if no labels exist in the DMAP, and the parameter section
of the cross reference will not contain any parameters although
parameters are present. An avoidance is to put a label in the DMAP.

Nastran Plotting — RF24D20, Superelement — Wrong Labels If SPC
labels at grid points are requested for plotting («GSPC») and
resequencing is requested, the SPC labels are attached to the wrong
components. An avoidance is to make a separate run for these plots
without resequencing, and insert an EXIT after the RFAlter, or not
request the SEKR operation in superelements. CR 1765 MSC / MD
Nastran Cyclic Symmetry — CYCLIC2 — UFM 3005, UFM 4319, UWM 4359
There are two errors related to the use of the CYSUP Bulk Data
entry when rotational symmetry is applied to a model with three or
more segments. 1. If the rigid body rotations are to be supported,
but there exists no stiffness at the components specified on the
CYSUP entry, then UFM 3005 may be issued. But, if components 4 and
5 (out-of-plane rotations) are then constrained by an SPCi card or
a GRID card, in order to avoid UFM 3005, then UFM 4319 will be
issued. For components 4 and 5, an avoidance of UFM 4319 is to
define rotational springs to ground (e.g., CELAS2). For component 6
(in-plane rotation), an avoidance of UFM 3005 is to apply a
single-point constraint (e.g., SPCi), which is contrary to Remark 1
under the CYSUP Bulk Data entry description. b. The specif

plate elements are present, and SHRINK or DIAG 34 are requested,
the error may occur. CR 1802 MSC / MD Nastran Miscellaneous —
Preface — CPU Loop If the THRU range on an input card is larger
than 131,071 for CDC/7600 and CYBER computers, or 8,388,608 for
CRAY computers, the error may occur. It has been observed on a
PLOAD2 card with a larger range. (Cyber,CDC 7600,CRAY only) An
avoidance is to split the THRU range into smaller sets, so that
none exceeds the limit. CR 1803 MSC / MD Nastran Elements — PQUAD4
— UFM 2010 If both PQUAD4 and PSHELL (and/or PCOMP) cards exist in
the same deck, the misleading message references PSHELL cards. The
PQUAD4 card is obsolete, and is removed from current documentation.
It should be replaced with the PSHELL card. The PQUAD4 card will be
deleted from the code on a future system. An avoidance is to
replace PQUAD4 card with PSHELL cards wherever they exist as they
cause various confusing errors. CR 1804 MSC / MD Nastran

MD Nastran Database — LOAD/UNLOAD — Wrong Answers If a database is
unloaded to a sequential file using the DBMGR //3 command, then
restored to a direct access file using the load command, any
keywords stored in the database dictionary will be lost. Most
keywords are only for diagnostic use (i.e., «SEMGDONE»), and will
cause no further errors. The one exception at present is the
keyword «NOSETRUE», which appears when all grid points are in the
residual structure. This will cause the fatal message above on
PARAM,NODATA or PARAM,DLOAD restarts. An avoidance is to use the
following alter for this type of restart: ALTER 10 $ MSC/61B, AFTER

Spectra — PARAM,RSPECTRA,0 — Wrong Answers The response spectra
option provided in transient analysis gives wrong answers for
acceleration spectra at high frequencies. The peak accelerations

transient analysis where a stiff spring and small mass have been
attached to the structure to directly represent the oscillator. The
displacement and velocity from the response spectra results will
match those of the oscillator represented with spring and mass.

for the highest frequency of interest.

Known Error Product Abstract

CR 1820 MSC / MD Nastran Database — DBSTORE — SFM 4167 The
maximum number of database dictionary entries is influenced by the
fourth input parameter for the DBMGR command when creating the
database. The default value will almost always result in more than
one GINO block being used for the dictionary. If the dictionary has
only one block, the database will be unusable. (Univac only) An
avoidance is to insure that the dictionary is assigned more than
one block. This can be determined from SIM 4162, under the
«WRITTEN» entry. This number should be greater than 1 when the
database is created. If it is not, increase the fourth input
parameter to at least twice the value printed under the «NUMBER OF

CR 1829 Any database file longer than 262, 143 PRUs may fail

specified in GINO blocks. A good approximation of the maximum
allowable number is one million/SYSBUF. (SYSBUF is the size of the
GINO buffer, which has a default of 1792.) Thus with default buffer
size, limit database files to about 8900 blocks. (CDC/Cyber running

Corrected Version 68

Known Error

CR 4701 in the FRRD1 module and the message «SYSTEM FATAL
MESSAGE 4276 QOPEN ERROR CODE 3012» is issued. This error occurs
when there are multiple calls to FRRD1 where the first call solves
for a single subcase (load case) or a single frequency and a
subsequent call solves for multiple frequencies and multiple
subcases (load cases). Avoidance: In Solution 26 the error may be
avoided by reordering subcases. The subcases that solve for
multiple frequencies and multiple subcases (load cases) must be
placed first in the Case Control Section.

CR 4721 MSC / MD Nastran Miscellaneous — Shell Script Error —
Unidentified Keyword on IBM RS/6000 An error exists in the IBM
RS/6000 operating system that causes the NASTRAN shell script to
incorrectly translate keywords resulting in an «unidentified
keyword» error message being output during submittal of the NASTRAN
job. The problem lies with the translate function. If a keyword is
specified in uppercase in the nast675rc file, then it will be
transposed by one character. The following example of the «tr»
command illustrates the error: echo «FrEd» | tr ‘[a-z]’ ‘[A-Z]’
gRfD Thus, the valid keyword SDIR is translated to «tejs» and an
unidentified keyword entry error results. Avoidance: This error may
be overcome by using the «tr -A» option.
