Goal-oriented model calibration using the adjoint framework
نویسندگان
چکیده
We define and analyze a goal-oriented procedure for model calibration in Computational Mechanics. In this procedure, priority is given in the updating to parameters which are the most influent to predict a given quantity of interest. The strategy uses the constitutive relation error framework as well as duality and adjoint techniques. The objective is thus to perform a partial model validation that enables to obtain the value of the quantity of interest with sufficient accuracy and minimal modeling effort.

Goal-oriented updating of mechanical models using the adjoint framework
In this paper, we introduce a goal-oriented procedure for the updating of mechanical models. It is based as usual on information coming from measurement data, but these data are post-processed in a convenient way in order to firstly update model parameters which are the most influent for the prediction of a given quantity of interest. The objective is thus to perform a partial model calibration...
متن کاملDevelopment of a framework to evaluate service-oriented architecture governance using COBIT approach
Nowadays organizations require an effective governance framework for their service-oriented architecture (SOA) in order to enable them to use a framework to evaluate their current state governance and determine the governance requirements, and then to offer a suitable model for their governance. Various frameworks have been developed to evaluate the SOA governance. In this paper, a brief introd...
متن کاملGoal-oriented Error Estimation for Free-boundary Problems Using the Exact Shape-linearized Adjoint
Since the late 1990s, goal-oriented error estimation and goal-oriented adaptive methods have been developed to control the discretization error in goal functionals of the solution1,2. These methods have mostly been applied to linear and nonlinear problems in solid and fluid mechanics. An important recent development is the extension of goal-oriented adaptive methods to multiphysics problems inv...

متن کاملGoal Oriented Mesh Adaptation without Fine Grid Interpolation for Finite-volume Cfd
In aeronautical CFD, engineers require accurate predictions of the forces and moments but they are less concerned with flow-field accuracy. Hence, the so-called "goal oriented" mesh adaptation strategies have been introduced to get satisfactory values of functional outputs at an acceptable cost, using local node displacement and insertion of new points rather than mesh refinement guided by unif...
