Stagg, Alan K.; Adams, Marissa B.P.; Bond, Stephen D.; Bova, Steven W.; Cearley, Griffin S.; Cochrane, Kyle; Crockatt, Michael M.; Gardiner, Thomas A.; Granzow, Brian N.; Hamlin, Nathaniel D.; Martin, Matthew R.; Shulenburger, Luke N.; Voth, Thomas E.; Weis, Matthew R.; Woolstrum, Jeffrey M.; Yusuf, Nedim A.

FLEXO (Flux-Limited Extended-MHD Ohm's Law) is a production-line multiphysics code developed at Sandia to enable more predictive modeling of target physics on pulsed-power devices. FLEXO uses an extended magnetohydrodynamics (XMHD) model which includes a generalized Ohm's law (GOL), an electron inertia term, and Hall physics. This report describes the code's numerical methods, its computational performance, and test problems of interest.
