Detailed Description

Member Data Documentation

◆ init_r

std::vector<double> rizer::ColumnOptions::init_r

Optional seed profile for the initial guess.

If non-empty (size >= 2, same length), it is interpolated onto the grid and overrides the default parabola

\[ T(r) = T_\text{wall} + (T_\text{center\_guess} - T_\text{wall}) \left(1-(r/R)^2\right) \]

Seeding with the analytical EH profile (or a linear ramp) helps Newton find the hot branch directly without expensive time-stepping. Optional seed radii [m], strictly increasing, spanning 0..R.

◆ init_T

std::vector<double> rizer::ColumnOptions::init_T

Optional seed temperatures [K] at each init_r location.

Definition at line 79 of file PlasmaColumnSolver.h.

◆ loglevel

int rizer::ColumnOptions::loglevel = 0
