THERM 2.0: a building component model for seady-satate two-dimensional heat transfer

THERM  2.0  is  a  state-of-the-art  software  program, available without cost,  that uses the finite-element method to model steady-state, two-dimensional heat- transfer problems. It includes a powerful simulation engine combined with a simple, interactive interface and graphic results. Although it was developed primarily to model thermal properties of windows, it is appropriate for other building components such as walls, doors, roofs, and foundations, and is useful for modeling  thermal  bridges  in  many  other  contexts, such as the design of equipment.
