desc.objectives.PlasmaVesselDistance.compute

PlasmaVesselDistance.compute(*args, **kwargs)[source]

Compute plasma-surface distance.

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:

d (ndarray, shape(surface_grid.num_nodes,)) – For each point in the surface grid, approximate distance to plasma.
