1.1. Fiesta¶

class vita.modules.equilibrium.fiesta.Fiesta(filename)¶

Class for tracing the magnetic field lines given a FIESTA equlibrium

Parameters:	filename (str) – the path to the FIESTA MATLAB save file.
Variables:	b_field (VectorFunction3D) – A 3D vector function of the magnetic field.

b_field¶: Function for getting the magnetic a 3D vector function of the magnetic field.

get_midplane_lcfs(psi_p=1.0005)¶

Function for getting the inner and outer radial position of the LCFS at the midplane

input: self, a reference to the object itself: psi_p, the flux surface of the LCFS, standard is psi_p = 1.005 (otherwise the field-line is located inside the LCFS)

return: Rcross, a list with the outer and inner radial position of the mid-plane LCFS

read_fiesta_model()¶

Function for reading the FIESTA equilibrium data from a .mat file

input: self, a reference the object itself

output: self.r_limiter, a numpy array with the radial coordinates of the vessel limits: self.z_limiter, a numpy array with the vertical coordinates of the vessel limits self.r_vec, a numpy array with the radial grid coordinates self.z_vec, a numpy array with the vertical grid coordinates self.psi, a numpy array with the flux coordinates self.psi_n, a numpy array with the normalised flux coordinate self.psi_axis, self.psi_lcfs, self.mag_axis, self.b_r, a numpy array with the radial magnetic field component self.b_z a numpy array with the vertical field component self.b_phi, a numpy array with the toroidal field component self.b_theta, a numpy array with the poloidal magnetic field component self.b_vac_radius, a self.b_vac, self.i_rod, a float with the current in the rod self.x_points, self.f_profile, self.q_profile, self.lcfs_polygon,

to_cherab_equilibrium()¶

Function for converting this Fiesta object to a CHERAB equilibrium.
