- boundaryThe list of boundary IDs from the mesh where this object applies
C++ Type:std::vector<BoundaryName>
Controllable:No
Description:The list of boundary IDs from the mesh where this object applies
- 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
EigenDirichletBC
EigenDirichletBC is provided for Eigenvalue solvers to handle Dirichlet boundary conditions for the right hand side. It is different from the regular Dirichlet BC. EigenDirichletBC will always return 0 regardless of the residual, and for the Jacobian matrix, the corresponding rows are totally zeroed out without adding one to the matrix diagonal.
