متن کاملQuelques résultats nouveaux sur les méthodes de projection
We revisit fractional step projection methods for solving the Navier–Stokes equations. We study a variant of pressure-correction methods and introduce a new class of velocitycorrection methods. We prove stability and O(δt) convergence in the L norm of the velocity for both variants. We also prove O(δt) convergence in the H norm of the velocity and the L norm of the pressure. We show that the ne...
متن کاملCohérences basées sur les valeurs en échec
In constraint satisfaction, basic inferences rely on some properties of constraint networks, called consistencies, that allow the identification of inconsistent instantiations or nogoods. Two main families of consistencies have been introduced so far : those that permit to reason from variables such as (i, j)-consistency and those that permit to reason from constraints such as relational (i, j)...
