To allow simulation of nanosecond scale plasma processes, we are developing a 3D fully relativistic fluid code with LTE (local thermal equilibrium) closure. This code is intended to be able to take output from PIC simulations as its initial state, to allow self-consistent simulation of processes acting over multiple time and density scales. In this code, both electrons and ions are treated as inertial fluids. Local fluid pressure is tied to the energy density using the Maxwell-Jüttner distribution, allowing investigation of the effect of local temperatures on, for example, the expanding sheath in TNSA (target normal sheath acceleration) experiments.
