Publisher description for HEAT2 Light
HEAT2 is a PC-program for two-dimensional transient and steady-state heat transfer. The program is along with the three-dimensional version HEAT3 used by more than 1000 consultants and 100 universities and research institutes worldwide. The program is validated against the standard EN ISO 10211 and EN ISO 10077-2. Features: - Well tested and robust PC-program. Well documented with a succinct theory. Easy to learn to use. Handy and rapid input due to an integrated pre-processor. Automatic mesh generation. Quick numerical method with optimization. Both steady-state and dynamic analysis. Multiple consecutive simulations may be started externally (batch mode). - Post-processor with extensive graphical capabilities of geometry, materials, numerical mesh, boundary conditions, temperature field, heat flow arrays and isotherms. Features: zooming, panning, rotation, color/gray-scale, high resolution printing. Arbitrary heat flows and temperatures can be recorded (transient calculations). Charts can be printed and exported in different formats (text, Excel, HTML, XML, Metafile, bitmap). The Movie Maker captures graphical output data, such as temperatures, isotherms, and heat flows to an AVI-file. - Any structure consisting of adjacent or overlapping rectangles with any combination of materials may be simulated. Up to 490000 (700·700) nodes may be used. - Boundary conditions may be a given heat flow, or a temperature with a surface resistance. Temperatures and heat flows may vary in time (sinusoidal, stepwise constant, stepwise linear). Several formats with climatic data such as TRNSYS, DOE, METEONORM, HELIOS, TMY2, SUNCODE, MATCH, and EXCEL can be imported for dynamic calculations - Available modifications: heat sources/sinks, internal boundaries of prescribed temperature, internal regions containing air or fluid of a single temperature, internal resistances, radiation inside cavities. - The Report Generator produces on-the-fly a printable document with optional text and figures with project info, and input/output data. - Automatic calculation of thermal coupling coefficient (L2D) and thermal transmittance (ψ) according to EN ISO 10211 for a wide variety of problems involving thermal bridges. - Material properties may easily be edited and added. Several material list are available. The default list Default.mtl contains about 200 common building materials. The list General.mtl has over 1200 defined materials. Another file with over 200 materials (in German) from the German standard DIN (Deutsches Institut für Normung, DIN V 4108-4) is also available. - Extensive window frame analysis has been implemented according to ISO 10077.
