Naming convention used in PLEQUE¶
Coordinates¶
Here presented naming convention is used to read/create input/output dict/xarray files.
- 2D
R
(default): Radial cylindrical coordinates with zero on machine axisZ
(default): Vertical coordinate with zero on machine geometrical axis
- 1D
psi_n
(default): Normalized poloidal magnetic flux with zero on magnetic axis and one on the last closed flux surface\(\psi_\mathrm{N} = \frac{\psi - \psi_\text{ax}}{\psi_\text{LCFS} - \psi_\text{ax}}\)
Fallowing input options are not implemented yet.
rho
: \(\rho = \sqrt{\psi_\text{N}}\)psi_1dprof
- poloidal magnetic flux; this coordinate axis is used only ifpsi_n
is not found on the input. Output files uses implicitlypsi_n
axis.
2D profiles¶
- Required on the input
psi
(Wb): poloidal magnetic flux
- Calculated
B_R
(T): \(R\) component of the magnetic field.B_Z
(T): \(Z\) component of the magnetic field.B_pol
(T): Poloidal component of the magnetic field. \(B_\theta =\text{sign\,} (I_p) \sqrt{B_R^2 + B_Z^2}\) Todo resolve the sign of B_pol and implement it!!!B_tor
(T): Toroidal component of the magnetic field.B_abs
(T): Absolute value of the magnetic field.j_R
(A/m2): \(R\) component of the current density. todo: Check the current unitj_Z
(A/m2): \(Z\) component of the current density.j_pol
(A/m2): Poloidal component of the current density.j_tor
(A/m2): Toroidal component of the current density.j_abs
(A/m2): Asolute value of the current density.
1D profiles¶
- Required on the input
pressure
(Pa)pprime
(Pa/Wb)F
: \(F = R B_\phi\)
- Calculated
pprime
: \(p \partial_\psi\)Fprime
: \(F' = \partial_\psi F\)FFprime
: \(FF' = F \partial_\psi F\)fprime
: \(f' = \partial_\psi f\)f
: \(f = (1/\mu_0) R B_\phi\)ffprime
: \(ff' = f \partial_\psi f\)rho
,psi_n
- Deriver
- q: safety factor profile
- qprime\(q' = \partial_\psi q\)
