  • Strictly speaking, walls that are not perpendicular to the plane of the splay and bend also involve twist. In keeping with tradition (cf. refs. 7) we also call these walls splay bend

  • A more obvious mechanism for growth of walls would be by propagation of splay-bend distortion from the end of the wall into the nematic bulk (since nematics transmit torques10b). The prolongation of the splay-bend distortion will focalize new flows which in their turn will enhance the newly created distortion, etc
