ForceBalanceAnisotropic.compute(*args, **kwargs)Source

Compute MHD force balance errors.

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).

• L_lmn (ndarray) – Spectral coefficients of lambda(rho,theta,zeta) – poloidal stream function.

• p_l (ndarray) – Spectral coefficients of p(rho) – pressure profile.

• a_lmn (ndarray) – Spectral coefficients of anisotropy term: beta_a = mu0 (p_{||} - p_{perp})/B^2

• i_l (ndarray) – Spectral coefficients of iota(rho) – rotational transform profile.

• c_l (ndarray) – Spectral coefficients of I(rho) – toroidal current profile.

• Psi (float) – Total toroidal magnetic flux within the last closed flux surface (Wb).

Returns:

f (ndarray) – MHD force balance error at each node (N).
