CST dipole simulation: Combine results tool different than export then manually combine results

[Ludovic_29]

Hello all,

I currently have a simulation of 3 dipoles with an excitation port for each one(see screenshot below):

If I run the simulation, the combination of both E field result at low frequency should give me a nice sphere.

For one dipole, this is the diagram I get from the simulation:

I have the same kind of results for the other dipoles but with a different oriented "null axis".

However, when I combine the results in post-processing > Combine Results with CST, I haven't the expected sphere. This is what I get:

When the data are exported to .csv files and manually combined, I have the expected sphere.

Does anyone have a clue about the reason the Combine results option give me this kind of result ?

Thx,

Ludovic.

Try simultaneous excitation to see the real pattern when 3 dipoles are excited.

Are you adding 3D vectorial components with magnitude and phase or just magnitudes in the manually exported combination? In the latter case, the result can't match real simultaneous excitation.
