Defines the data set to be read from the results file.
Lstep
Load step number of the data set to be read (defaults to 1):
| — | Read load step |
FIRST | — | Read the first data set ( |
LAST | — | Read the last data set ( |
NEXT | — | Read the next data set ( |
PREVIOUS | — | Read the previous data set ( |
NEAR | — | Read the data set nearest to |
LIST | — | Scan the results file and list a
summary of each load step. ( |
Sbstep
Substep number (within Lstep
). Defaults to the last substep of the load step (except in a buckling
or modal analysis). For a buckling (ANTYPE,BUCKLE)
or modal (ANTYPE,MODAL) analysis, Sbstep
corresponds to the mode number. Specify Sbstep
= LAST to store the last substep for the specified
load step (that is, issue a SET,Lstep
,LAST command).
If Lstep
=
LIST, Sbstep
= 0 or 1 lists the basic step
information. Sbstep
= 2 also lists the
basic step information, but includes the load step title, and labels
imaginary data sets if they exist.
Fact
Scale factor applied to data read from the file. If zero (or blank), a value of 1.0 is used. This scale factor is only applied to displacement and stress results. A nonzero factor excludes non-summable items.
Harmonic velocities or accelerations
can be calculated from the displacement results from a modal (ANTYPE,MODAL) or harmonic (ANTYPE,HARMIC)
analysis. If Fact
= VELO, the harmonic
velocities (v) are calculated from the displacements (d) at a particular
frequency (f) according to the relationship v = 2 πfd. Similarly,
if Fact
= ACEL, the harmonic accelerations
(a) are calculated as a = (2 πf)2d.
If Lstep
= LIST in an analysis using
rezoning, Fact
across all rezoning data
sets is listed.
KIMG
Used only with complex results (harmonic and complex modal analyses).
0 or REAL | — | Store the real part of complex solution (default). |
1, 2 or IMAG | — | Store the imaginary part of a complex solution. |
3 or AMPL | — | Store the amplitude |
4 or PHAS | — | Store the phase angle. The angle value, expressed in degrees, will be between -180° and +180°. |
TIME
Time-point identifying the data set to be read. For a harmonic analyses, time corresponds to the frequency.
For a buckling analysis, time corresponds to the load factor.
Used only in the following cases: If Lstep
= NEAR, read the data set nearest to TIME
. If both Lstep
and Sbstep
are zero (or blank), read data set at time = TIME
.
Do not use TIME
to identify the data
set to be read if you used the arc-length method (ARCLEN) in your solution.
If TIME
is between two solution time
points on the results file, a linear interpolation is done between
the two data sets (except in rezoning).
Solution items not written to the results file (OUTRES) for either data set will result in a null item after data set interpolation.
If TIME
is beyond the last time point
on the file, the last time point will be used.
If TIME
is between two solution time
points and both Lstep
and Sbstep
are zero (or blank), no interpolation is performed
for the PRCINT/PLCINT commands.
(That is, for results generated by the CINT command,
only the data set associated with the lower of the solution time points
is used.)
ANGLE
For harmonic elements (PLANE25,
PLANE75, PLANE78,
PLANE83, and SHELL61),
ANGLE
specifies the circumferential location (0.0 to 360°)
used when reading from the results file. The harmonic factor (based on the circumferential
angle) is applied to the displacements and element results, and to the applied constraints and
loads which overwrites any values existing in the database. If
ANGLE
= NONE, all harmonic factors are set to 1 and postprocessing
yields the solution output.
When using ANGLE
= NONE with MODE
>
0, the combined stresses and strains are not valid.
The default value of ANGLE
is 0.0; however if the
SET command is not used, the effective default is NONE.
For full harmonic analyses with the amplitude option (KIMG
= 3
or AMPL), ANGLE
is the prescribed phase angle at which the
amplitude is computed.
NSET
Data set number of the data set to be read. If a positive value for
NSET
is entered, Lstep
,
Sbstep
, KIMG
, and
TIME
are ignored. Available set numbers can be determined by
SET,LIST.
ORDER
Key to sort the harmonic index results. This option
applies to cyclic symmetry buckling and modal analyses only, and is
valid only when Lstep
= FIRST, LAST, NEXT,
PREVIOUS, NEAR or LIST.
ORDER | — | Sort the harmonic index results in ascending order of eigenfrequencies or buckling load multipliers. |
(blank) | — | No sorting takes place. |
Defines the data set to be read from the results file into the
database. Various operations may also be performed during the read
operation. The database must have the model geometry available (or
use the RESUME command before the SET command to restore the geometry from Jobname.DB). Values for applied constraints [D] and loads
[F] in the database will be replaced by their corresponding
values on the results file, if available. (See the description of
the OUTRES command.) In a single load step analysis,
these values are usually the same, except for results from harmonic
elements. (See the description of the ANGLE
value above.)
In an interactive run, the sorted list (ORDER
option) is also available for results-set reading via a GUI pick
option.
You can postprocess results without issuing a SET command if the solution results were saved to the database file (Jobname.DB). Distributed ANSYS, however, can only postprocess using the results file (for example, Jobname.RST) and cannot use the Jobname.DB file since no solution results are written to the database. Therefore, you must issue a SET command or a RESCOMBINE command before postprocessing in Distributed ANSYS.
When postprocessing amplitudes or phases (KIMG
= AMPL or PHAS):
The only appropriate coordinate system is the solution coordinate system (RSYS ,SOLU). For layered elements, a layer (LAYER) must also be specified. When displaying the displacement amplitudes, use a contour display (PLNSOL command). Because a deformed shape display (PLDISP command) could lead to a non-physical shape, the displacement scaling is off by default (/DSCALE,,OFF).
The conversion is not valid for averaged results, derived results (such as principal stress/strain, equivalent stress/strain, and USUM), or summed results obtained using FSUM, NFORCE, and PRNLD.
Cyclic symmetry results are not supported.
