[Gmsh] Scalar product of complex vector fields from different views in Gmsh ?

[Zacharie De Grève]

Dear Gmsh users, dear developers,

Is it possible to compute a scalar product of complex vector fields contained 
in different views with Gmsh ? 

In fact, I would like to compute a magnetic energy density wm as the volume 
integral of the scalar product of two fields coming from different 
frequency-domain FE resolutions, 1 and 2, as follows : 

wm_1,2=1/2 * Int (b_1*conj(h_2)) dv,

where b_1 and h_2 are complex vector fields.

I have seen that the plugin "Integrate" can be used for the integration, but 
what plugin should I use for the scalar product between the two complex 
vector fields, including the conjugate complex operation ? Maybe 
the "Evaluate" plugin is appropriate for this task, but I can not figure out 
how to do it, since different "Time-step"-s as well as 
different "Component"-s are involved at the same time.

Thank you very much for your help !
