Gravity (g)

Generates the OpenFOAM g file that defines the gravitational acceleration vector.

Type: openFOAM.constant.g

Parameters

Parameter	Type	Default	Description
x	number	0	Gravitational acceleration in x direction [m/s²]
y	number	0	Gravitational acceleration in y direction [m/s²]
z	number	-9.8	Gravitational acceleration in z direction [m/s²]

Output

Field	Description
Result	The rendered g file content

Example

{
    "Gravity": {
        "Execution": {
            "input_parameters": {
                "x": 0,
                "y": 0,
                "z": -9.81
            }
        },
        "type": "openFOAM.constant.g"
    }
}

Note

Required for buoyancy-driven simulations (e.g., Boussinesq approximation) and Lagrangian particle tracking.
