Displays results as vectors.
ItemPredefined vector item (from Table 213: PLVECT - Valid Item Labels below) or a label identifying the i-component of a user-defined vector.
Lab2Label identifying the j-component of a user-defined
vector. In most cases, this value must be blank if Item is selected from Table 213: PLVECT - Valid Item Labels. Individual principal
stresses (Item = S) or principal strains
(Item = EPxx) may be plotted by specifying the value as 1, 2, or 3.
Lab3Label identifying the k-component of a user-defined
vector. Must be blank if Item is selected
from list below or for 2-D user defined vector.
LabPLabel assigned to resultant vector for display labeling
(defaults to Item).
ModeVector or raster mode override key:
(blank) | — | Use the setting of |
RAST | — | Use raster mode for PLVECT displays. |
VECT | — | Use vector mode for PLVECT displays. |
LocVector location for display of field element results:
ELEM | — | Display at element centroid (default). |
NODE | — | Display at element nodes. |
Nodal results quantities will only be displayed at nodes, not at element centroids.
EdgeEdge display override key:
(blank) | — | Use the setting of Key on the /EDGE command. |
OFF | — | Deactivate the edge display. |
ON | — | Activate the edge display. |
KUNDUndisplaced shape key:
0 | — | Display vectors on undeformed mesh or geometry. |
1 | — | Display vectors on deformed mesh or geometry. |
Displays various solution results as vectors (arrows) for the
selected nodes and/or elements (elements must contain at least three
nodes that are not colinear). For example, PLVECT,U displays the displacement vector for all selected nodes. For
section displays [/TYPE], the vectors are shown
only on the section face (i.e., cutting plane). The PLVECT display of principal strains and stresses (Item = S, EPTO, EPEL, EPPL, EPCR, or EPTH) on a "cut" of the model (/TYPE,,1 ,5,7,8, or 9) is not supported. The resulting
plot displays the vectors on all selected elements, not on just the sliced surface. See the /VSCALE command to scale vector lengths. Vector magnitudes
may be shown as a contour display with the PLNSOL command. Various results also depend upon the recalculation method
and the selected results location [LAYER, SHELL, and NSEL].
Items may be selected from a set of recognized vector labels
(Item) or a vector may be defined from
up to three scalar labels (Item,Lab2,Lab3). Scalar labels
may be user-defined with the ETABLE command. The
vectors appear on an element display as arrows showing the relative
magnitude of the vector and its direction. The predefined items will
be shown either at the node or at the element centroid, depending
on what item is being displayed and depending on the Loc setting. User defined ETABLE items will be shown at the element centroid, regardless of the Loc setting. Stress vectors appear as arrows at the
element centroid, with the arrowheads pointing away from each other
for tension and toward each other for compression.
For PowerGraphics, vector arrow displays are generated in Global Cartesian (RSYS = 0). All subsequent displays will revert to your original coordinate system.
When vector mode is active (Mode =
VECT), use the Z-buffered display type [/TYPE,,6]
to maximize speed of PLVECT plots (other hidden
display types may make plotting slow). For PowerGraphics [/GRAPHICS,POWER], the items marked with [1] are not supported by PowerGraphics.
It is possible to plot principal stresses (Item = S) or principal strains (Item = EPxx) individually. To do so, specify a Lab2 value of 1, 2, or 3. For example, the following
are valid commands:
| PLVECT,S,1,,,VECT,ELEM,ON,0 |
| PLVECT,EPEL,3,,,VECT,NODE,ON,0 |
Table 213: PLVECT - Valid Item Labels
| Item | Description |
|---|---|
| Valid item labels for nodal degree of freedom vector results are: | |
| U | Structural displacement vector. |
| ROT | Structural rotation vector. |
| V | Velocity vector. |
| A | Magnetic vector potential vector. |
| FFLX | Fluid flux in poromechanics. |
| Valid item labels for structural element results are: | |
| S | Principal stresses [1]. |
| EPTO | Principal total strain (EPEL + EPPL + EPCR) [1]. |
| EPEL | Principal elastic strains [1]. |
| EPPL | Principal plastic strains [1]. |
| EPCR | Principal creep strains [1]. |
| EPTH | Principal thermal strains [1]. |
| EPDI | Principal diffusion strains [1]. |
| Valid item labels for field element results are: | |
| TG | Thermal gradient vector. |
| TF | Thermal flux vector. |
| PG | Pressure gradient vector. |
| EF | Electric field vector. |
| D | Electric flux density vector. |
| H | Magnetic field intensity vector. If Lab2 is blank, then Item is interpreted as one of the predefined labels. Otherwise, Item is interpreted as a user-defined ET label and ANSYS will request a nonblank Lab2/Lab3 according to the dimension of the problem. |
| B | Magnetic flux density vector. |
| CG | Concentration gradient vector. |
| DF | Diffusion flux density vector. |
| FMAG | Electromagnetic force vector. |
| P | Poynting vector. |
| JS | Source current density vector for low-frequency magnetic analyses. Total current density vector (sum of conduction and displacement current densities) in low frequency electric analyses. |
| JT | Total measureable current density vector in low-frequency electromagnetic analyses. (Conduction current density vector in a low-frequency electric analysis.) |
| JC | Conduction current density vector for elements that support conduction current calculation. |
