Simplifications have been made where possible, as permitted by the new $<type>var syntax. Duplication has been reduced in similar blockMesh files (e.g., sloshingTank cases). Settings that cannot practically be changed have been hard-coded (e.g., angle in the mixerVessel2D blockMeshDict). The rotor2D blockMeshDict has been centralised and extended to work with an arbitrary number of rotor blades.
