When using 'simple' or 'hierarchical' decomposition it is useful to slightly rotate a coordinate-aligned block-mesh to improve the processor boundaries by avoiding irregular cell distribution at those boundaries. The degree of slight rotation is controlled by the 'delta' coefficient and a value of 0.001 is generally suitable so to avoid unnecessary clutter in 'decomposeParDict' 'delta' now defaults to this value.
