- ANISOS (Utility Menu> PlotCtrls> Animate> Isosurfaces) produces an animated sequence of an
isosurface of contoured deformed shape in POST1. Before using ANISOS, you must execute a display
command that contains contouring. - ANMODE (Utility Menu> PlotCtrls> Animate> Mode Shape) produces an animated sequence of a
deformed mode shape in POST1. Before using ANMODE, you must execute a command that contains
deformation. - ANMRES (Utility Menu>PlotCtrls>Animate>Animate Over Results) produces an animation of results
over multiple results files in an explicit dynamic structural analysis or fluid flow analysis with
remeshing in POST1. - ANTIME (Utility Menu> PlotCtrls> Animate> Over Time) produces an animated sequence of a
contoured deformed shape varying over time in POST1. Before using this macro, you must execute
a display command that contains deformation, contouring, or both and you must have a solution
containing time variance.
ANDYNA, while still supported by ANSYS, has been replaced by the ANDATA macro.
17.4. Capturing Animated Display Sequences Off-Line
In this procedure, you produce graphics images one at a time, photographing or video-recording them
frame by frame. Among this technique's advantages is the fact that when you capture an animated
sequence one frame at a time, there is generally no limit on its complexity, and performance does not
degrade with increasing numbers of entities.
In general, producing high-quality graphics video recordings is a job for multimedia experts with spe-
cialized equipment. Capturing a sequence of individual frames on video requires three separat e pieces
of equipment:
- A device that produces a television-style video signal (accomplished through the use of an add-in
board, a separat e encoder, or a scan converter). - A frame controller to control the video recorder as it captures the individual frames. The frame con-
troller receives both the television video signal and a computer input (such as serial RS-232), and
sends instructions to capture the frames. - A frame-controllable video recorder (which differs considerably from a home VCR).
In addition to specialized hardware requirements, some custom software is also needed for video re-
cording. The /SYS command in ANSYS provides the programming interface between the ANSYS program
and these special systems, allowing video system commands to be integrated into your ANSYS session.
Another hardware solution for animation is capturing single frames onto film, using a device known as
a film recorder. As with video frame-capture equipment, images are saved onto film under software
control. The best of these devices can be expensive, and custom programming may be involved in using
them.
A relatively low-cost approach to film recording involves the use of a stationary camera shooting indi-
vidual frames from a graphics display. These frames are then processed as the individual frames of a
film. The resources of photographic technicians are often required to turn still images into acceptable-
quality moving film.
