◆ linitialize

integer inputlist::linitialize = 0

Used to initialize geometry using a regularization / extrapolation method.

if Linitialize = \(-I\) , where \(I\) is a positive integer, the geometry of the \(i=1,N_V-I\) surfaces constructed by an extrapolation
if Linitialize = 0, the geometry of the interior surfaces is provided after the namelists in the input file
if Linitialize = 1, the interior surfaces will be intialized as \(R_{l,m,n} = R_{N,m,n} \psi_{t,l}^{m/2}\), where \(R_{N,m,n}\) is the plasma boundary and \(\psi_{t,l}\) is the given toroidal flux enclosed by the \(l\)-th interface, normalized to the total enclosed toroidal flux; a similar extrapolation is used for \(Z_{l,m,n}\)
Note that the Fourier harmonics of the boundary is always given by the Rbc and Zbs given in physicslist.
if Linitialize = 2, the interior surfaces and the plasma boundary will be intialized as \(R_{l,m,n} = R_{W,m,n} \psi_{t,l}^{m/2}\), where \(R_{W,m,n}\) is the computational boundary and \(\psi_{t,l}\) is the given toroidal flux enclosed by the \(l\)-th interface, normalized to the total enclosed toroidal flux; a similar extrapolation is used for \(Z_{l,m,n}\)
Note that, for free-boundary calculations, the Fourier harmonics of the computational boundary are always given by the Rwc and Zws given in physicslist.
if Linitialize = 1, 2, it is not required to provide the geometry of the interfaces after the namelists
