Implementation and assessment of an extended hydrogenic molecular model in UEDGE

Autor: W.H. Meyer, T.D. Rognlien, A. Holm

Two sets of pure deuterium plasmas are simulated using UEDGE, one including atoms and molecules and the other including atoms only as separate fluid species. Simulation results in one and two dimensions are reported to assess the role of molecules in
