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.
 

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.
