MultiGrid Error

[lusabato]

In the transverse electric field of the beam, a Multigrid can be chosen and a rectangular grid can be given as target grid input (target_grid_beam). When one of the two dimensions of the rectangular target grid input is too small compared to the other one, you can get this error (you can find attached the beam.beam (beam_error.beam.txt) file and the chamber (FCC_ee_chamber_09mm.mat.txt) used for the simulation):

ValueError: The internal grid is outside the chamber!

Increasing the value of the smallest dimension of the rectangular target grid, you can avoid the error (you can find attached the beam.beam (beam_corrected.beam.txt) file).
