Kindly help me building a user defined function for following inlet velocity conditions....

"The velocity inlet has a time varying velocity imposed at the start of the solution in the form of a full period sinusoid with an amplitude of 0.05m/s and frequency of 3200Hz. After the sinusoid is complete the velocity remains zero at the inlet for remainder of solution."

Depends on what software and language you have to use are using:

0[m/s] + step((1/3200)-t/1[s])*0.05[m/s]*sin(2*3.14159265*3200*t)

t <= (1/3200)s
