    "description": "The `BuildConstraintSystemEndEvent` is an event in the SOFA simulation framework, specifically within the `sofa::simulation` namespace. Its primary role is to signal the end of the process of building the constraint system for simulations involving constraints and their resolutions. This event inherits from the generic `Event` class and does not have any specific data fields or links.\n\nThis component interacts with other components through the SOFA API by being part of the event handling mechanism, which is crucial for coordinating various stages in simulation pipelines. Methods such as `getEventTypeIndex`, `checkEventType`, and `GetClassName` allow for type checking and identification within the framework's event system.\n\nPractical usage involves integrating this event into the simulation process where constraint systems are constructed and resolved. Since it does not contain any specific data fields, its interaction with other components is primarily through inheritance and method overrides in the context of SOFA’s event-driven architecture."

    "maths": "The `BuildConstraintSystemEndEvent` is an event in the SOFA simulation framework that signifies the completion of the process for building constraint systems within a simulation involving constraints and their resolutions. This event is part of the broader variational/Lagrangian mechanics framework implemented by SOFA, but it does not directly contribute to the governing equations or operators (such as mass matrix $M$, stiffness matrix $K$, internal force $f_{\\text{int}}$, residual $R$, etc.) nor does it encode any constitutive or kinematic laws. Instead, its primary role is coordination within the global FEM pipeline.\n\n### Role in the Global FEM Pipeline\n- **Assembly**: This event is not involved directly in the assembly of matrices or forces but rather acts as a signal for post-processing steps related to constraints.\n- **Time Integration**: The `BuildConstraintSystemEndEvent` does not contribute to time integration schemes such as implicit Euler or Newmark-type methods. It merely indicates that the constraint system has been fully constructed, which may then be solved during subsequent stages of simulation.\n- **Nonlinear Solve**: While it does not participate directly in solving nonlinear equations, this event signals when the constraint system is ready for solution steps involving Lagrange multipliers and saddle-point problems.\n- **Linear Solve**: Similarly, the event does not contribute to linear solvers but indicates that the necessary constraint systems are prepared for those steps.\n- **Constraint Handling**: It plays a role in ensuring that all constraints have been accounted for by signaling when their system has been built. Constraint Jacobians and related matrices would be part of this process.\n\n### Numerical Methods or Discretization Choices\nThe `BuildConstraintSystemEndEvent` does not encode specific numerical methods or discretization choices. It is a higher-level construct that coordinates these aspects through the SOFA event-driven architecture.\n\n### Variational / Lagrangian Mechanics Framework\nIn the context of variational and Lagrangian mechanics, this event supports the broader framework by ensuring all necessary constraint systems are built before proceeding with further simulation steps such as time integration or nonlinear solve. This ensures consistency in enforcing kinematic constraints within the simulation pipeline."
