Topology optimization with adaptive mesh refinement
We outline a robust method for topology optimization with adaptive mesh refinement and derefinement (AMR). Since the total volume fraction in topology optimization is usually modest, after a few initial iterations the domain of computation is largely void. It is inefficient to have many small elements in such regions, as these contribute significantly to the overall computational cost but littl...
متن کاملDynamic Adaptive Mesh Refinement for Topology Optimization
We present an improved method for topology optimization with both adaptive mesh refinement and derefinement. Since the total volume fraction in topology optimization is usually modest, after a few initial iterations the domain of computation is largely void. Hence, it is inefficient to have many small elements, in such regions, that contribute significantly to the overall computational cost but...
متن کاملStress and fatigue constrained topology optimization
This thesis concerns structural optimization in conceptual design stages, for which constraints that are adapted to industrial requirements have been developed for topology optimization problems. The objective of the project has been to identify and solve problems that today prevent structural optimization from being used in a broader sense in the avionic industry; the main focus has been on st...
متن کاملInexact Restoration and Adaptive Mesh Refinement for Constrained Optimal Control
A new adaptive mesh refinement algorithm is proposed for solving Euler discretization of stateand control-constrained optimal control problems. Our approach is designed to reduce the computational effort by applying the inexact restoration (IR) method, a numerical method for nonlinear programming problems, in an innovative way. The initial iterations of our algorithm start with a coarse mesh, w...
متن کاملOptimization and Evaluation of a Titanium Adaptive Mesh Refinement Code
Adaptive Mesh Refinement (AMR) is a grid-based approach to approximating the solutions to partial differential equations (PDEs). It is governed by the principle that some portions of the grid require more computation to solve than other regions. AMR uses an adaptive approach to adjust the resolution of the computational domain to reflect the varying computational needs. A highperformance implem...
