review text: The finite electron mass streamlined Darwin field (SDF) model is derived for a quasineutral plasma and contrasted to the SDF model for a nonneutral plasma. Because the Darwin model is used, the Courant numerical stability condition \(c\Delta t/\Delta x<1\) is avoided. In a quasineutral plasma, the \(\omega_{pe}\Delta t<2\) stability condition and the \(\Delta x/\lambda_{De}<1\) accuracy condition are avoided by the use of a quasineutral Poisson equation. A fast coupled-elliptic solution technique also works well with the quasineutral SDF model.
