Optimising the icosahedral grid

Efficient parallel computations in THOR require global domain decomposition of the grid. In our model we take the advantage of the geometrical properties of the icosahedron which can be divided into 10 rhombuses as shown in the figure. The rhombuses can be then easily divided into smaller sub-domains (smaller rhombuses) which are essential to optimize the simulations.
