  In preparation for extending the JOREK nonlinear MHD code to stellarators, a
hierarchy of stellarator-capable reduced and full MHD models has been derived
and tested. The derivation was presented at the EFTC 2019 conference.
Continuing this line of work, we have implemented the reduced MHD model
(arXiv:1907.12486) as well as an alternative model which was newly derived
using a different set of projection operators for obtaining the scalar momentum
equations from the full MHD vector momentum equation. With the new operators,
the reduced model matches the standard JOREK reduced models for tokamaks in the
tokamak limit and conserves energy exactly, while momentum conservation is less
accurate than in the original model whenever field-aligned flow is present.
