Algorithm Options

The following inputs must be preceded by “incflo.”

Description

Type

Default

advection_type

Advection scheme (options: Godunov, MOL, BDS)

string

Godunov

advect_momentum

Advect momentum (otherwise use convective differencing)

bool

false

advect_tracer

evolve the tracer equation(s)?

bool

false

trac_is_conservative

Is tracer conserved? If specified, one entry required per tracer

int

1

ntrac

number of tracers

int

1

constant_density

Only evolve the continuity equation if false

bool

true

rho_0

density (if constant)

Real

1.0

diffusion_type

Diffusion type (0 = Explicit, 1 = Crank-Nicholson, 2 = Implicit)

int

2 (Implicit)

mu

viscosity (if constant)

Real

1.0

mu_s

scalar diffusivity

Real(s)

0.0

use_cc_proj

Use cell-centered rather than nodal pressure; this changes the which approximate projection we use

bool

false

use_tensor_solve

In velocity solve, use multicomponent \(\nabla \cdot \tau\) otherwise use separate solves for each velocity component

bool

true
