- lambdaLagrange multiplier variable
C++ Type:std::vector<VariableName>
Description:Lagrange multiplier variable
- variableThe name of the finite volume variable this kernel applies to
C++ Type:NonlinearVariableName
Description:The name of the finite volume variable this kernel applies to
FVScalarLagrangeMultiplier
This object implements the residuals that enforce the constraint
using a Lagrange multiplier approach. E.g. this object enforces the constraint that the average value of match .
The detailed description of the derivation for the corresponding finite element constraint can be found at scalar_constraint_kernel. The finite volume version can be obtained by simply substituting for . Note that .
