  Here we present first results simulating plasma filaments in non-axisymmetric
geometries, using a fluid turbulence extension of the \boutxx~framework. This
is made possible by the implementation of the Flux Coordinate Independent
scheme for parallel derivatives, an extension of the metric tensor components
which allows them to vary in three dimensions, and development of grid
generation. Tests have been performed to confirm that the extension to three
dimensional metric tensors does not compromise the accuracy and stability of
the associated numerical operators. Recent changes to the FCI grid generator in
\boutxx, including a curvilinear grid system which allows for potentially more
efficient computation, are also presented. Initial simulations of seeded plasma
filaments in a non-axisymmetric geometry are reported. We characterize
filaments propagating in the closed-field-line region of a low-field-period,
rotating ellipse equilibrium as inertially-limited by examining the velocity
scaling and currents associated with the filament propagation. Finally, it is
shown that filaments in a non-axisymmetric rotating ellipse equilibrium
propagate in a toroidally nonuniform fashion, and it is determined that the
long connection lengths in the scrape-off-layer enable parallel gradients to
establish, which has consequences for interpretation of experimental data.
