Discretization of Cost and Sensitivities in Shape Optimization

چکیده
We consider a problem in aircraft engine testing [1], [6]. Of special concern is the influence of the aircraft forebody on the flow that reaches the engine intake. Modern aircraft are too large to place in a wind tunnel; there may not even be room for just the forebody and engine. Resourceful engineers build small “forebody simulators” that roughly reproduce the flow disturbances known to be caused by the real forebody. A typical setup is shown in Figure 1. Designing an effective simulator this way is crude, tedious, and expensive, and computational guidance is desired. This paper investigates computational difficulties arising in a simplified version of this design problem.

متن کاملAerodynamic Shape Optimization Using a Cartesian Adjoint Method and CAD Geometry
We present a new approach for the computation of shape sensitivities using the discrete adjoint and flow-sensitivity methods on Cartesian meshes with general polyhedral cells (cutcells) at the wall boundaries. By directly linearizing the cut-cell geometric constructors of the mesh generator, an efficient and robust computation of shape sensitivities is achieved. We show that the error convergen...
متن کاملEFFICIENT SIMULATION FOR OPTIMIZATION OF TOPOLOGY, SHAPE AND SIZE OF MODULAR TRUSS STRUCTURES
The prevalent strategy in the topology optimization phase is to select a subset of members existing in an excessively connected truss, called Ground Structure, such that the overall weight or cost is minimized. Although finding a good topology significantly reduces the overall cost, excessive growth of the size of topology space combined with existence of varied types of design variables challe...
متن کاملControl of the finite element discretization error during the convergence of structural shape optimization algorithms
This work analyzes the influence of the discretization error contained in the Finite Element (FE) analyses of each design configuration proposed by structural shape optimization algorithms over the behaviour of the algorithm. If the FE analyses are not accurate enough, the final solution will neither be optimal nor satisfy the constraints. The need for the use of adaptive FE analysis techniques...
متن کاملIsogeometric shape optimization of shells using semi-analytical sensitivity analysis and sensitivity weighting
We present isogeometric shape optimization for shell structures applying sensitivity weighting and semi-analytical analysis. We use a rotation-free shell formulation and all involved geometry models, i.e., initial design, analysis model, optimization model, and final design use the same geometric basis, in particular NURBS. A sensitivity weighting scheme is presented which eliminates certain ef...
