I am undertaking a project on oscillating cylinders. Currently i have completed my work on longitudinal oscillation with a help of UDF code.
I have to continue my work with transverse oscillation now. i dont know how to change the UDF code. Can u pls help me.

This is the code i used for longitudinal oscillation. can anyone please help me to make it transverse.

real fr=1;/* insert frequency ratio */
real fo=4.45;/* vortex shedding frequency for stationary cylinder*/
real w = 2*M_PI*fo*fr;
real x_cg[3];
/*NV_S(cg_vel, =,0.0);*/
cg_omega[0]= 0.0;
cg_omega[1]= 0.0;
cg_omega[2]=0*cos(0.5*t);
cg_vel[0]= 0.002*w*cos(w*t);
cg_vel[1]= 0.0;
cg_vel[2]= 0.0;
