'anim' 'tune' <value>|'steps' <value>|'time' <value>|-> 'real' ['on'|'off']|'model' ['on'|'off']| -> 'elem' ['on'|'off']This keyword is used to manipulate the animation of displacements. See also ''ds'' and ''scal''. The amplification is controlled with ``tune''. ``steps'' defines the number of frames over one periode. ``time'' controlls the duration of one periode. ``real'' switches of the automatic amplification and the real displacements are used instead. In addition the displacements of the negative part of the periode is set to zero. ``model'' switches the static model (undeformed) edges on or of. ``elem'' does this for the element edges.
