Quick start

To run the model, open rhombus.pro with Gmsh.

Additional information

The model automatically computes the photonic crystal fibre band diagram of Figure 3.16, p. 152 from the textbook Foundations Of Photonic Crystal Fibres [1], using a finite element formulation with Floquet-Bloch conditions [2]. You can double-click on any point in the diagram to visualize the corresponding eigenmode, even while the calculation is running.
