Mechanical APDL Basic Analysis Guide - Ansys

Note
The commands discussed in this section, unless otherwise noted, are DISPLAY commands, not
ANSYS commands.
1. Set up your DISPLAY session with the /SHOWDISP and (if desired) /CMAP or NOCOLOR commands.
(You can include these commands in a start130.dsp file.)
2. Using the FILEDISP command, direct the DISPLAY program to read the desired neutral graphics file.
If you are using the DISPLAY and ANSYS programs simultaneously, make sure the neutral graphics file
is first closed in ANSYS. That is, issue /SHOW,CLOSE (in ANSYS) before reading the file in DISPLAY.
3. Specify terminal options with the TERM command. For screen display, you might be interested in
setting the TERM,LOOP options (the number of loops, NLOOP, and the amount of time to pause
between displays, PAUSE).
4. Issue the PLOT command to cause specified displays to be formed. Recall that your graphics file can
contain several different displays. You can call up specific displays by number, or you can instruct the
program to display ALL plots found on your file.
5. Issue FINISH to exit the DISPLAY program.
18.3.3. Viewing Animated Sequences on a Screen
The procedure for creating an animated display in the DISPLAY program is similar to that used in the ANSYS
program. By executing /SEG and ANIM commands, you can display several frames in rapid succession to
achieve an "animation" effect. (As in the ANSYS program, with the DISPLAY program you cannot use all
hardware platforms to produce online animation.)
For the DISPLAY program, the Aviname and DELAY arguments of the /SEG command are ignored.
GUI menu paths to the /SEG and ANIM commands are:
Command(s): /SEG, ANIM
GUI: Utility Menu> PlotCtrls> Redirect Plots> Delete Segments
Utility Menu> PlotCtrls> Redirect Plots> Segment Status
Utility Menu> PlotCtrls> Redirect Plots> To Segment Memory (UNIX)
Utility Menu> PlotCtrls> Redirect Plots> To Animation File (Windows)
The same comments regarding memory requirements for ANSYS animation also apply for the DISPLAY program.
A typical command stream for animation would look like this:
/SEG,DELE ! Deletes all currently stored segments
/SEG,MULTI ! Stores subsequent displays in segment memory
PLOT,4,8,1 ! Plots #4 - #8 (5 frames total) are stored in segment
! memory (Use PLOT,ALL to include every plot)
/SEG,OFF ! Turn off the frame-capture function
ANIM,10 ! Cycles through the five frames 10 times
18.3.4. Capturing Animated Sequences Offline
18.3.4. Capturing Animated Sequences Offline
You can use the DISPLAY program to capture animation offline (on film or videotape) in much the same
way as you would do for the ANSYS program. See Animation (p. 267) for a general discussion of this technique.
