Equations

The solver evolves a scalar, \( T \), using the equation:

\[ \ddt{T} - \div (D_T \grad T) = S_T \]

Input requirements

Mandatory fields:

• Transported field: T: scalar [-]

Physical models

• Transport $FOAM_CASE/constant/transportProperties requirements:

  // Diffusion coefficient [m2/s]
  DT              4e-05;
  

Solution controls

$FOAM_CASE/system/fvSchemes requirements:

• time schemes: ddt(T)
• gradient schemes: grad(T)
• laplacian schemes: laplacian(DT,T)

$FOAM_CASE/system/fvSolution requirements:

• solver entry for T
