Formulation of ENLIL: Solving the Equations • The temperature is calculated from an equation of state p = 2nkT where n is the number density. • Available in Cartesian or spherical coordinates. • Uses the Total-Variation-Diminishing Lax-Fredrich scheme. • No artificial diffusion. • Second order accurate. • Field-interpreted central-difference approach is used to solve for B so that ∇ ⋅B = 0 • Uses adaptive mesh.
Launch a CME into the Streamer Belt • Most CMEs are launched into the coronal streamer belt. •Launch an over-pressured spherical plasmoid into tilted, slow and dense streamer belt. • Launch CME at fast SW speed which is twice slow SW speed.
