desc.objectives.Elongation.compute

Elongation.compute(*args, **kwargs)[source]

Compute elongation.

Parameters:

  • R_lmn (ndarray) – Spectral coefficients of R(rho,theta,zeta) – flux surface R coordinate (m).

  • Z_lmn (ndarray) – Spectral coefficients of Z(rho,theta,zeta) – flux surface Z coordinate (m).

Returns:

elongation (float) – Elongation, dimensionless.
