Introduction

This page documents the contents of a vacuum namelist input file. Vacuum namelist variables are defined in the vacuum_main_nli common block.

Namelist Variables

Input variable

Description

Code Reference

Filename variables

coils_dot_file

File name for the mgrid namelist input file.

vacuum_input::coils_dot_file

Array allocation sizes.

n_extcur

Size of the extcur array

vacuum_input::n_extcur

Equilibrium variables

extcur

Array of external currents.

vacuum_input::extcur

Shifts and rotations of external coils.

cg_shift_1	Vector to shift all the coils. (Before rotation)	vacuum_input::cg_shift_1
cg_rot_theta	Spherical polar angle to specify axis of rotation.	vacuum_input::cg_rot_theta
cg_rot_phi	Spherical azimuthal angle to specify axis of rotation.	vacuum_input::cg_rot_phi
cg_rot_angle	Angle to rotate about axis of rotation. NB - LEFT HAND convention. Put left thumb along axis of rotation, fingers indicate direction of positive rotation.	vacuum_input::cg_rot_angle
cg_rot_xcent	Position of center of rotation.	vacuum_input::cg_rot_xcent
l_rot_coil_center	Chooses the center of rotation. True - use current-averaged center of coil-group for center of rotation. False - use position specified in cg_rot_xcent for center of rotation.	vacuum_input::l_rot_coil_center
cg_shift_2	Vector to shift all the coils. (After rotation)	vacuum_input::cg_shift_2
