Recent new releases of COMSOL provide the user with a dramatic new interface from which to interact, and many new features “under the hood” for solving problems more efficiently and with even greater accuracy and consistency than before. This paper will explore several of these new version 4+ features for the conjugate heat transfer class of problems. Our environment is unique in that we demand high-quality solutions for nuclear-reactor systems and the models tend to become large and difficult to solve. One area investigated is the new distributed parallel processing capability on our small cluster. Most of our flow is turbulent and requires knowledge of the solution up to and through the wall condition. Therefore the new Low-Reynolds number extension to the turbulence models is of strong importance to our work.
