2D energy, angular distribution

I am trying to use the 2D energy angular distribution set-up, The results i’m getting are very far from the case of 1D which are fitting the exp. data. Do you have an idea why the 2D set up doesn’t work ?

Thank you very much, have a great day,

hello,I don‘t know how to use Hall thruster model. Can you give me a instruction or a numerical example with the thruster.
Thank you!
