Incompressible Flow Code

DNS/LES Code

  • This code solves the three-dimensional, unsteady, incompressible Navier-Stokes equations with and without heat transfer equation.
  • Fractional Step Method (FSM) with three options
    • Semi-implicit method with Runge-Kutta3 + Crank-Nicolson method (Le & Moin, JCP 1991)
    • Fully implicit method with Crank Nicolson method (Choi & Mopin, JCP 1994)
    • Linearised fully implicit method with Crank Nicolson method (Kim et al., IJNMF 2001)
  • Immersed Boundary Method (IBM) for block treatment
