Role of INRIA:

Sensitivity computations based on discrete equations

The contribution of INRIA is focalised on the application of the symbolic Differentiation tool ODYSSEE to the assembly of the different parts of the objective functional gradient, which involves the adjoint state equation residual and the sensitivity of the state equation residual with respect to shape parameters.

Optimisation algoritms and strategies

INRIA contribution concentrates on new gradient based optimisation strategies for solving constrained optimisation problems. This involves the treatment of the state equation as an equality constraint, and the application of interior nodes methods to inequality constraints.
