Hi @momchil-flex . Please let me know what you think when you have some time:

Actually, are you sure about the distinction from PlaneWave? Now that I think about it I'm a little confused about this, because the auxiliary simulation to the TFSF one just uses a PlaneWave. I thought that the difference is only in the area factor.

FilipeFcp commented 1 week ago

Hi Momchil. Yes, I understand that the difference is the area factor. A PlaneWave (infinity with periodic boundary) will inject 1 W of power. A TFSF will inject 1 $\frac{W}{\mu^2}$ intensity, or 1/sourceArea power.

Regarding the FAQ, it is describing a num_freq attribute for the SourceTime object, that seems deprecated. Is the normalization still an issue for frequencies distant from the central one? Can I remove the reference for the num_freq attribute?
