◆ apply()

void CurrentDrive::apply	(	const Grid< DeviceType > &	grid,
		Plasma &	plasma,
		Smoothing &	smoothing,
		const Moments &	f0_moments,
		const DomainDecomposition< DeviceType > &	pol_decomp,
		const MagneticField< DeviceType > &	magnetic_field,
		const GridField< HostType, VarType::Scalar, PhiInterpType::None, TorType::OnePlane, KinType::DriftKin > &	loop_voltage_h,
		LoopVolDiagnostics &	loop_vol_diag,
		int	gstep,
		double	time
	)

Drives electron current such that the plasma current required by the Grad-Shafranov equilibrium magnetic field is maintained. The plasma current is \(j_{\parallel,0} = \hat{\boldsymbol{b}}\cdot\left(\nabla\times\boldsymbol{B}_0\right)/\mu_0 \), or \(j_{\parallel,0} = \sum_s (q_s n_s u_{\parallel,s}) \). Therefore, \(u_{\parallel,e}=j_{\parallel,0}-\sum_{ions}(q_s n_s u_{\parallel,s}) \). The actual electron flow is stored in f0_moments.u_local). Any difference between the targeted and actual flow is damped away with an exponential damping \(\partial u/\partial t = \gamma (u_{target}-u_{actual}) \).
