Abstract
This report deals with the topology optimization of convection problems.That is, the aim of the project is to develop, implement and examine topology optimization of purely thermal and coupled thermomechanical problems,when the designdependent eects of convection are taken into consideration.This is done by the use of a selfprogrammed FORTRANcode, which builds on an existing 2Dplane thermomechanical nite element code implementing during the course `41525 FEMHeavy'. The topology optimizationfeatures have been implemented from scratch, and allows the program to optimize elastostatic mechanical problems, steadystate thermal problems and coupled thermomechanical problems, for a range of objective functions subjected to a volumefraction constraint. The programme utilises the GCMMA algorithm, by K. Svanberg, to optimize the given problems. Designdependent side convection has been formulated and implemented, where the convection is interpolated into the designdomain and applied upon the boundaries of the design using a densitybased interpolation function.The implementation has been tested for both pure thermal analysis, along with thermal and thermomechanical optimization. The solutions to the test problems show interesting results, that underline the signicance of including convection and the designdependent eects thereof.
