"Case": {
    "SetOfEquations": {
        "Momentum": {
            "Equation": "NSPrimitive",
            "Variable": "u"
        },
        "Energy": {
            "Equation": "primitive-p",
            "Variable": "T"
        }
    }
}

The parameter is provided as a dictionary whose entries define:

  • the equation type,

  • the specific form (in cases where several variations exist),

  • the associated transported variable.

Each equation sub-block contains:

  • "Equation": equation model used by FELiCS,

  • "Variable": corresponding transported variable name.

Notes#

The variables defined in SetOfEquations should be consistent with other configuration parameters such as:
