abstract = {<p style="text-align: justify;">We derive and numerically solve a surface active nematodynamics model.
We validate the numerical approach on a sphere and analyse the influence of hydrodynamics on the oscillatory motion of topological defects. For ellipsoidal surfaces the
influence of geometric forces on these motion patterns is addressed by taking into account the effects of intrinsic as well as extrinsic curvature contributions. The numerical
experiments demonstrate the stronger coupling with geometric properties if extrinsic
curvature contributions are present and provide a possibility to tune flow and defect
motion by surface properties.</p>},
