ANFLOW, NFRAM, DELAY, NCYCL, TIME, SPACING, SIZE, LENGTH
Produces an animated sequence of particle flow in a flowing fluid
or a charged particle traveling in an electric or magnetic field.
NFRAMNumber of frames captured (defaults to 5).
DELAYTime delay during animation (defaults to 0.1 seconds).
NCYCLNumber of animation cycles (defaults to 5). Non-UI mode only.
TIMETotal Trace Time (seconds) (defaults to 0, which is the full flow trace).
SPACINGParticle spacing in seconds (defaults to 0).
SIZEParticle size (defaults to 0, which is a line).
LENGTHParticle length fraction (defaults to .1).
ANFLOW invokes an ANSYS macro which produces an animation of particle flow in a flowing fluid or charged particle motion in an electric or magnetic field by the last plot action command (i.e., PLTRAC). This command is only operational on graphic display platforms supporting the /SEG command. After executing ANFLOW, you can replay the animated sequence by issuing the ANIM command. This command is functional only in the Postprocessor.
The TIME option lets you set the time interval
of forward travel for the trace.  The SPACING option
is used to define the particle spacing in seconds from adjacent particles
in the stream line.  The SIZE variable sets the
radius of the particle.  The LENGTH variable is
used to define the particle length fraction.  By default, the LENGTH is
set to .1, which means the particle occupies 10% of the flow region and the
other 90% is a color-code line.  The SPACING and LENGTH variables
only make sense when the SIZE variable is nonzero
(i.e., the particle is bigger than the line).
