• Fixed viscous forces calculation in high order solver which were a factor of 2.0 too large
• Upgraded versions of CUDA, Intel MPI and MKL used. CUDA 9.2 is now required for GPU runs
• Added validate_input script to allow checking of control dictionary before run time
• Enforce input parameters that are either True or False to be booleans when validating the dictionary. i.e. 'true' is no longer valid
• Changed colour of timer breakdown output to improve readability
