Important Reminder
Because this is an axisymmetrical problem, many quantities are affected by a 2π factor of symmetry, such as the impedance, for instance.
Always make sure to verify that the factor of symmetry is properly taken into account.
Generally speaking, all results in the ATILA-GiD interface are provided without correction for the factor of symmetry.
