For many kinds of materials (e.q. metals, shape memory alloys, etc.), thermal changes coupled with the deformation process can have significant effect on the mechanical response and also on the accuracy of numerical analysis. In order to take them into account, monolithic coupling algorithms have been used, however a partitioned approach can also be applied. An advantage of the partitioned thermo-mechanical coupling is the possibility to re-use already developed software to simulate various kinds of multiphysics scenarios, i.e. various coupled fields: structure, heat transfer, fluids, magnetic, etc. To realize the partitioned approach, communication protocols for exchange of information between the used codes are needed [1]. To this end, Component Template Library (CTL) [2], developed at the Institute of Scientific Computing, TU Braunschweig, Germany, is used as a middleware between the FEM programs for the structural analysis (PAKS) and the heat transfer analysis (PAKT).
