In the case of incompressible flow, the level set method does not ensure mass conservation and it has to be enforced. The usual global mass conservation presents unacurracy in the case of separated phases of one fluid. In this paper, we propose an alternative local mass conservation based local volume fluxes. We apply our method to test cases...

This lecture is devoted to the presentation of two particular "hierarchical" approaches to numerical shape optimization in aerodynamics design: 1) multilevel parametric shape optimization algorithms; 2) additive preconditioners. The first approach is inspired from the classical geometrical multigrid method, except that here the geometrical...
