Periodic load using a defined function?

I would like to solve a time dependent problem. For that I would like to define a periodic load on one of the boundaries in my geometry. My question is if it is possible to first define a function, e.g. "Model -> Definitions -> Functions ->Waveform -> Triangle" and then use this function as a time dependent load? I have tried to do that by first defining a waveform function called "wv1". But when I put "wv1" in the "Boundary Load", the line turns red and the solver gives me an error saying that it failed to evaluate variable wv1.
Thanks in advance,
Yuriy

"ww1" is not a "variable", it's an "operator", you should use it as ww1(t[1/s]) the t[1/s] is to make the time "t" unitless as operators want unitless input

Good luck
