Overview🔗

• Category: Basic
• Steady state or transient

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
