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.

In the latter case, the result can't match real simultaneous excitation. Upvote 0 Downvote
