For body force load contours, use /PBF (Utility Menu> PlotCtrls> Symbols)./PBF applies to finite-
element loads only; body force symbols do not appear in solid model displays./PBF does not produce
an "immediate" display.
You can also use the /PBF command to display your current density magnitude as a vector instead of
a contour./PBF, JS, 2 will display the current density magnitude as vector arrows along the surface.
The length of the arrows is proportional to the current density magnitude.
You will typically use the above commands to turn load symbols on for visual verification when you
apply the loads in SOLUTION (or PREP7).The ANSYS program automatically turns these symbols off
when you enter POST1. See Creating Geometric Results Displays (p. 269) for more information on con-
trolling postprocessing displays.
13.2.4.2. Displaying Boundary Condition Values Next to a Symbol
You can display load symbols by using the /PBC command. (See Turning Other Symbols On and
Off (p. 268) for information on turning other symbols on and off.) This command also provides an option
that lets you display the boundary condition values next to the symbols. Some of the boundary condition
values that are associated with this command include reaction force (RFOR), reaction moment (RMOM),
displacement (U), and current flow (AMPS).
Since your applied forces/moments can differ by orders of magnitude from your derived forces/moments,
you can use the FBCS option of the /PSYMB command to determine the basis of the Force Boundary
Conditions Scaling of your display.
See the Command Reference for more information about the various boundary values that are supported.
13.2.4.3. Displaying Boundary Condition Symbols for Hidden Surfaces
When there are hidden surfaces, 2-D drivers will display your boundary condition symbols, yielding a
confusing display. In some instances, however, you may desire to see them.You can use the /HBC
command to control BC symbol display. The default setting is to NOT display boundary condition
symbols on the hidden surfaces (/HBC, WN, OFF).You can set the display ON or OFF individually for
each window of your display. 3-D are not controlled by this command. This function is accessed from
the Utility Menu> PlotCtrls> Style> Hidden Line Options area of the GUI.
13.2.4.4. Scaling Vector Load Symbols
/VSCALE (Utility Menu> PlotCtrls> Style> Vector Arrow Scaling) allows you to adjust the scale of
vector item symbols (such as the arrows representing concentrated forces, etc.). This same command
also allows you to choose a "uniform scaling" option, in which all items' vector symbols have the same
length, regardless of their relative magnitudes.
13.2.4.5. Turning Other Symbols On and Off
You can turn symbols for master degrees of freedom, coupled nodes, and nodes in constraint equations
on and off with the /PBC command. Use the /PSYMB command (Utility Menu> PlotCtrls> Symbols)
to turn symbols on and off for local, nodal, and element coordinate systems, line directions, keypo-
ints/nodes, and layer orientation (for layered elements).
