enter POST1. See Creating Geometric Results Displays (p. 249) for more information on controlling 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. 248)
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, keypoints/nodes, and
layer orientation (for layered elements).
