(Ask)How to implement a time-dependent velocity profile periodicly?
 
Hello everyone,
I am stuck here about how to implement the time-dependent velocity profile periodically. The inlet velocity is "V0+0.005sin(2pi St t)"

I have created the velocity profile. Now I want to ask FLUENT to read it every 20 time steps.
I supposed to use "Execute Commands" option, but I don`t know how to input the text command under the command" list. Could you please help me out?
Thank you in advance.
my email is lzhuowei@pi.ac.ae
