only wall-4 you don't need use stationary set layering

you can use in-cilinder for tests or try this udf

#include "udf.h"

static double linear;

DEFINE_CG_MOTION(linear, dt, vel, omega, time, dtime) { real w = 300,a=0.1;

NV_S (omega,=, 0.0);

linear = w*sin(w*CURRENT_TIME); vel[0] = linear; }

0 is the direction of moving

0 is x 1 is y 2 is z
