A brief discussion on energy needs and the role plasma physics plays in fusion and energy production, including an introduction to computational plasma physics. Leading the development of an algorithm for modeling two species plasmas, evolving the number density, flow velocity, and temperature equations coupled to Maxwell’s field equations, making special note of the inclusion of the displacement current. A discussion on the normal modes in cold and hot plasmas, as represented by dispersion relations resulting from a linear analysis of the two fluid equations. Consideration given to the ideas of geometry, temporal and spatial discretization, linearization and finite element expansion using the NIMROD code structure. Discussion of future stability analysis.
