ADEqualValueEmbeddedConstraint

This is a constraint enforcing overlapping portions of two blocks to have the same variable value

This version of EqualValueEmbeddedConstraint uses automatic differentiation, see EqualValueEmbeddedConstraint for information on formulation.

warningwarning:ADEqualValueEmbeddedConstraint only works for PENALTY formulation

Automatic differentation cannot be used to compute Jacobian terms for "formulation" = KINEMATIC because the KINEMATIC implementation enforces the constraint by enforcing the residual value on the secondary node prior to application of the constraint, in EqualValueEmbeddedConstraint, Eq. (1). This secondary node residual value is a nonAD copy of the residual and cannot be used to compute derivatives for the Jacobian.
