Mapdl.ancyc(numframes='', kcycl='', delay='', **kwargs)#

Applies a traveling wave animation to graphics data in a modal cyclic symmetry analysis.

Mechanical APDL Command: ANCYC

Command default:

The default ancyc command (issuing the command with no arguments) specifies these implicit argument values: ancyc, 18, 0, 0.1

Parameters:
numframesstr

The number of plot frames for the animation. Valid values range from 5 through 36. The default is 18. A low value (because it specifies fewer graphical frames) produces a rougher animation but loads faster. A high value produces a smoother animation but requires more time to load.

kcyclint or str

The animation mode:

  • 0 - Continuous animation cycle (forward-reverse-forward).

  • 1 - Discontinuous animation cycle (forward-reset-forward). This option is the default.

delaystr

The time delay (in seconds) between animation frames. Valid values range from 0.1 through 1.0. The default is 0.1 seconds, which produces a seemingly real-time animation. A higher value produces a slower animation.

Notes

The ancyc command is valid in a modal cyclic symmetry analysis only.

The command animates the cyclic symmetry mode shape plot in the General Post Processor ( post1 ). When you issue a nodal- or element-results plot command (for example, plnsol, plesol, or pldisp ) and then issue the ancyc command, Mechanical APDL applies a traveling wave animation to the mode shape plot.

Each frame of the animation is created by expanding the cyclic symmetry mode shape at increasing phase angles (via the cycexpand command) starting at zero in equal increments over 360°. The phase-angle increment is 360 / NUMFRAMES.

The animation display shows the traveling wave of the result quantity being plotted. The traveling wave animation is applicable only to nodal diameters (harmonic indices) greater than 0 and less than N / 2 (where N is the number of cyclic sectors in the model).
