Equations

The solver employs the SIMPLE algorithm to solve the continuity equation:

$$\div \u = 0$$

and momentum equation:

$$\div ( \u \otimes \u ) - \div \vec{R} = - \grad p + \vec{S}_u$$

Where:

$\u$ : Velocity

$p$ : Kinematic pressure

$\vec{R}$ : Stress tensor

$\vec{S}_u$ : Momentum source

Input requirements

Mandatory fields:

• p: Kinematic pressure [m2/s2]
• U: velocity [m/s]

Physical models

• turbulence: constant/turbulenceProperties
• finite volume options: constant/fvOptions (optional)

Solution controls

$FOAM_CASE/system/fvSchemes requirements:

• time schemes: steadyState
• gradient schemes: grad(U), grad(p)
• divergence schemes: div(phi,U)
• note: Bounded schemes for steady state
• laplacian schemes: laplacian(nuEff,U), laplacian((1|A(U)),p)

$FOAM_CASE/system/fvSolution requirements:

• solver entries for U, p
