OVERFLOW
- Abstract
- OVERFLOW is a thin-layer Navier-Stokes flow solver
for structured grids. It can use single block grids
or Chimera overset grid systems. Right-hand side options
include central differencing with Jameson 4/2 dissipation
and Roe upwinding. Left-hand side options include the
Pulliam-Chaussee diagonalized (scalar pentadiagonal)
scheme and the LU-SGS scheme. Low-Mach number preconditioning
is available for accuracy in computing low-speed steady-state
flows. First-order implicit time advance is used. A
time-accurate mode is available, or local timestep
scaling can be selected for acceleration to steady
state. Grid sequencing and multigrid are also implemented
for convergence acceleration.
