How to enter time-dependent functions in comsol.

Hi everybody

In this moment I´m working with simulations to effects of fault current in bus bars, this waveform of current [in the worst case] have the following form:

i(t) = sqrt(2)Ik[sin(wt+phi)-sin(phi-theta)exp(-k*t)]

were:

Ik = Current peak [A] w = angular frecuency [rad] phi and theta = Are angles [rad] k = Is a constant

I tried to introduce this form of current by multiple forms: - Variable (Global definitions) - Functions (Global definitions)

And then insert it into the physical perspective

I appreciate very much if you help me detect the errors that I may be committing

Try to make the definions under Component, not globally.
