Detailed Description

////////////////////////////////////////////////////////////////////// //////////////////////////////////////////////////////////////////////

Base class for interface elements that allow the application of a volume constraint on the region bounded by these elements. The elements must be used together with the associated VolumeConstraintElement which stores the value of the target volume. Common functionality is provided in this base for storing the external "pressure" value that is traded for the volume constraint.
