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
