We report results from a dynamic approach to equilibrium for a three-fluid solar-wind model in quasi-spherical 1D. We advance the mass, momentum and energy transport equations for protons, alpha particles and electrons with full interspecies Coulomb collisional coupling. We include electron heat conduction and use an ambipolar electric field in place of the negligible electron momentum coupling. A parametrized coronal heat source supplies energy to the electrons near the solar surface. At the inner boundary (the solar surface) we specify the inflow velocity, mass flux and temperature for each species, and at the outer boundary (at large radius) we allow the fluids to flow freely from the computational domain. Starting from an initial wind model (e.g., single fluid) we evolve to a three-fluid steady state. We will describe comparisons with Bürgi's 1992 static equilibrium results.
