What advection and transient scheme should I use for a DES simulation?

  You should typically choose a ‘High Resolution’ or ‘Specified Blend Factor’ scheme for the advection, and the ‘Second Order Backward Euler’ scheme for the transient discretization. With this the solver will use the following: – a ‘High Resolution’ or ‘Specified Blend Factor’ scheme for the momentum equations in the RANS region, – a ‘Central Difference’ scheme in the LES region. – an upwind scheme for the turbulence equations everywhere – a second order transient scheme on the momentum – a first order transient on the turbulence model
