Spatial and Temporal Discretization

• x1 and x2 directions:

  • generalized coordinates
  • fully staggered
  • formulated in terms of volume flux.
  • Second-order central difference scheme for all terms

• x3 direction:

  • planar
  • Co-located arrangement
  • dealiased Fourier spectral collocation method.

• 2nd order accurate fractional step scheme in time

  • RK3 for non-linear terms
  • CN for viscous terms
