AverageValueConstraint

This Kernel implements part of the equation that enforces the constraint of

where is a given constant, using a Lagrange multiplier approach. The residual of the Lagrange multiplier is given as:

(1)

In particular, this Kernel implements the residual contribution for the in Eq. (1). See also ScalarLagrangeMultiplier for the residual of the variable .

The detailed description of the derivation can be found at scalar_constraint_kernel.
