  The FuZE sheared-flow-stabilized Z pinch at Zap Energy is simulated using
whole-device modeling employing an axisymmetric resistive magnetohydrodynamic
formulation implemented within the discontinuous Galerkin WARPXM framework.
Simulations show formation of Z pinches with densities of approximately 10^22
m^-3 and total DD fusion neutron rate of 10^7 per {\mu}s for approximately 2
{\mu}s. Simulation-derived synthetic diagnostics show peak currents and
voltages within 10% and total yield within approximately 30% of experiment for
similar plasma mass. The simulations provide insight into the plasma dynamics
in the experiment and enable a predictive capability for exploring design
changes on devices built at Zap Energy.
