For the development and design process of new products and components, finding the best possible layout is of great importance. Topology optimisation offers the opportunity to get an initial topology, i.e. learning where to place material and where to put cavities. The finite element software ANSYS offers a tool for topology optimisation, but regarding to the further processing of the solution only in a very limited way. An algorithm was developed, in which the numerical computing environment MATLAB does the optimisation routine. Both systems operate simultaneously and work together. The thesis includes the introduction of several theoretical approaches and their evaluation, the implementation of the programme und numerical tests.
