A map of the operations necessary to calculate the effect of on the current in a second order scheme. The top row shows the algorithm for , which requires a total of 11 operations. The bottom row is for or and it requires a total of 17 operations.
An initial Maxwellian plasma (solid black line) heated by the inverse bremsstrahlung operator (broken blue line) or a dipole electric field (dotted red line). The inverse bremsstrahlung operator recovers the shape of the DLM 11,12,19,23 distribution function calculated using a dipole electric field.
Four non-local transport simulations using different numbers of spherical harmonics and projected onto a Cartesian mesh. A plasma with density , and initial temperature 1 keV is heated from the left with an inverse bremsstrahlung source with profile and . This set of simulations shows that convergence can be achieved when sufficient number of spherical harmonics is used.
The ratio of the effective heat conduction coefficient from VFP simulations to the Spitzer and Härm value, , is shown with red squares as a function of the wavenumber of the temperature perturbation. We have also overlaid a blue solid line that corresponds to expression (22) in the text. Good agreement between the VFP results and expression (22) is observed for .
The corona of a planar solid-density target is heated by a source with intensity . The pressure and temperature profiles, as well as the longitudinal electric ( ) and transverse magnetic ( ) fields are shown after 10 ps and 20 ps.
