◆ 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_wall + (T_center_guess - T_wall)*(1-(r/R)^2). Seeding with the analytical EH profile (or a linear ramp) helps Newton find the hot branch directly without expensive time-stepping. seed radii [m], strictly increasing, 0..R
