Introduction
This document outlines the integration of ANSYS Workbench with VisualDOC for optimization tasks, focusing on wing shape optimization. It provides an overview of the tools and methodologies used in the process.
Problem Setup and Parametrization
The process begins by treating the ANSYS analysis as a black box. Parameters are specified within ANSYS Workbench, and VisualDOC is used to call ANSYS, extract variables, and classify them into input and output files. The optimization runs with ANSYS Workbench in batch mode, and design history is plotted with concurrent monitors.
Optimization Settings
The objective is to maximize the lift-to-drag ratio, with constraints on stress and deflection. Design variables include geometrical dimensions.
Analysis on the Optimized Wing Shape
The document discusses the results of the optimization process, highlighting improvements in the wing shape.
VisualDOC - Multidiscipline Design Optimization
VisualDOC is a software system that facilitates optimization in design tasks through a graphical interface and various optimization methods, including gradient-based and non-gradient-based approaches.
