MakeFlowDispersion¶

Prepares flow fields for dispersion simulations by extracting and transforming data from a base flow solution.

Type: openFOAM.dispersion.MakeFlowDispersion

Parameters¶

Parameter	Type	Default	Description
`baseFlow`	object	—	Base flow case configuration (see below)
`dispersionFields`	object	`{"CellHeights": {}}`	Fields to generate for dispersion
`Hmix`	object	`{"internalField": 1000}`	Mixing height field definition
`ustar`	object	`{"internalField": 0.1}`	Friction velocity field definition

baseFlow¶

Field	Type	Default	Description
`name`	string	`"../flow/simpleStation"`	Path to the base flow case
`useTime`	number	`50`	Time step to extract from the flow solution
`maximalDispersionTime`	number	`3600`	Maximum time for the dispersion simulation [s]

Output¶

Field	Description
`casePath`	Path to the prepared dispersion case directory

}

Note

This node integrates with the Hera toolkit to prepare flow fields. It optionally runs the indoorDistanceFromWalls OpenFOAM utility when the buildDistanceFromWalls flag is enabled.
