A coupled thermo-fluid-structure interaction approach, consisting of a Cartesian grid finite volume scheme with conservative interface method for the fluid and a finite element scheme for the thermo-structure interaction problem, is proposed. We present a loosely coupled approach for the solution of the thermo-fluid-structure interaction problem based on a Dirichlet-Neumann partitioning. The structural surface is represented by a level set function in the fluid code. The velocity and temperature field required for the coupling are interpolated from structural values on the zero-contour level set surface. Data transfer between the two codes is performed via message passing interface. The proposed method is tested for a cooling-process of a heated metal bar by means of an external laminar boundary layer flow. Results show that the presented approach is able to handle the complexity of the three-field problem.     «
