- lambdaLagrange multiplier variable
C++ Type:std::vector<VariableName>
Unit:(no unit assumed)
Controllable:No
Description:Lagrange multiplier variable
- variableThe name of the variable that this residual object operates on
C++ Type:NonlinearVariableName
Unit:(no unit assumed)
Controllable:No
Description:The name of the variable that this residual object operates on
FVIntegralValueConstraint
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 .
warningwarning
The contribution to the diagonal of the system of this kernel is null, which introduces a saddle point. Make sure to use a NONZERO shift in your preconditioner.
Example input syntax
In this example, the average value of the variable v is set using a FVIntegralValueConstraint. In combination with a single Dirichlet boundary condition, this makes the numerical problem accept a single numerical solution, and be well-posed.
