    • In nematic droplets with homeotropic anchoring a twist in the director field is usually observed (see [33]). We are currently investigating the dipole of Figure 1 and also find a twisting of the director field close to the hyperbolic hedgehog. However, for the Frank elastic constants of 5CB the distance of the defect from the surface of the water droplet differs only by 10% if the director field is not allowed to twist. We do not expect a different behavior in the geometry under consideration in this article. Performing an advanced numerical investigation of such a complex geometry, we want to concentrate, as a first step, on the principal features of the system. Therefore, we neglect twist deformations to simplify the numerics. The same simplification to catch the main behavior of nematic drops in a magnetic field was used by other authors, see, e.g., [38].
