BoundaryCondition Class

The BoundaryCondition class contains methods and properties for defining boundary condition values and directions. Note that some properties and methods are not applicable to all boundary condition types.

Note that boundary conditions are applied using the Scenario method “applyBoundaryCondition(bc object)”.

BoundaryCondition Class Methods

BoundaryCondition Methods	Description	data return
bc = new BoundaryCondition(type)	creates a boundary condition object of name bc (can be anything); type = string	no
setValue(value, units)	sets value and units; value = number, units = string	no
setReferenceTemperature(value, units)	Sets reference temperature for film coefficient	no
setPointOnAxis(x,y,z) setAxisDirection(x,y,z)	sets axis properties for rotational velocity; x, y, and z are numbers	no
setTimeCurve(tc)	sets transient boundary condition; tc = time curve object	no
setBackgroundTemperature(value, units)	sets transparency background temperature; value = number; units = string	no
getFanCurve()	Returns fan curve for an external fan curve BC	yes
