The time-averaged Poynting vector (if you want the power flow) is given by Re(S)
See the Wikipedia article (https://en.wikipedia.org/wiki/Poynting_vector) for more detail.
EDIT: this post was corrected to reflect the notations used in Sim4Life, namley that S(x,y,z,f0) is already the time-averaged quantity and includes the factor 1/2.
