Clarification about Thermal Plot (Resultant Heat Flux)?

Hi all,

I wanted to get some clarification about the Resultant Heat Flux thermal plot that you can generate from a transient thermal study.  The reported results are in W/m^2, and I have it set to display just one time step at a time.  My question is, I do not understand what "area" they are considering for the m^2 part...is it the area of one element of a mesh?  Basically what I would like to do is calculate the power (and then, heat) of the system from this plot, but I haven't been able to figure out what SW defines as flux.  Any help please?

(Using SW2010 btw)
