Simulation results of the fabrication of tubular hollow core fiber. Animation illustrates the evolution of the structure as it is drawn down from the preform to the fiber. Pressure is applied to the capillaries to stop surface tension collapsing them, this can lead to the phenomena of mid-draw contact. Here we show how it can be avoided by increasing the fiber draw tension. Part of Fig. 5.
