A class that is used to implement the constraint that the fluid volume in a region bounded by associated FaceElements (attached, e.g., to the mesh boundaries that enclose a bubble) must take a specific value. This GeneralisedElement is used only to store the desired volume and a pointer to the (usually pressure) freedom that must be traded for the volume constraint. More...

Detailed Description

A class that is used to implement the constraint that the fluid volume in a region bounded by associated FaceElements (attached, e.g., to the mesh boundaries that enclose a bubble) must take a specific value. This GeneralisedElement is used only to store the desired volume and a pointer to the (usually pressure) freedom that must be traded for the volume constraint.

◆ VolumeConstraintElement() [1/2]

oomph::VolumeConstraintElement::VolumeConstraintElement ( double * prescribed_volume_pt )

Constructor: Pass pointer to target volume. "Pressure" value that "traded" for the volume contraint is created internally (as a Data item with a single pressure value)

	)

Constructor: Pass pointer to target volume, pointer to Data item whose value specified by index_of_traded_pressure represents the "Pressure" value that "traded" for the volume contraint. The Data is stored as external Data for this element.
