1-19390023 Documentation/QRG - CQUAD4 differential stiffness
remark obsolete
Remark 6 for CQUAD4 should now read:
..."The specification of offset vectors gives wrong results in solution
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.
