![]() You may have entered a wrong volumetric heat capacity. My transient calculation takes long time.Another file with over 200 materials (in German) from the German standard DIN (Deutsches Institut für Normung, DIN V 4108-4) is also available.īelow are some frequently asked questions for HEAT2 and HEAT3. The list General.mtl has over 1200 defined materials. The default list Default.mtl contains about 200 common building materials. Material properties may easily be edited and added.Automatic calculation of thermal coupling coefficients(L 3D) according to EN ISO 10211 for a wide variety of problems involving thermal bridges.The Report Generator produces on-the-fly a printable document with optional text and figures with project info, and input/output data.Available modifications: heat sources/sinks, internal boundaries of prescribed temperature.Several formats with climatic data such as TRNSYS, DOE, METEONORM, HELIOS, TMY2, SUNCODE, MATCH, and EXCEL can be imported for dynamic calculations Temperatures may vary in time (sinusoidal, stepwise constant, stepwise linear). Boundary conditions may be a given heat flow, or a temperature with a surface resistance.Up to 50 million nodes may be used (requires a PC with 3 GB RAM). Any structure consisting of adjacent or overlapping rectangles with any combination of materials may be simulated. ![]() ![]() Charts can be printed and exported in different formats (text, Excel, HTML, XML, Metafile, bitmap). Arbitrary heat flows and temperatures can be recorded (transient calculations). Features: zooming, panning, rotation, color/gray-scale, high resolution printing. Post-processor with extensive graphical capabilities in 2D and 3D of geometry, materials, numerical mesh, boundary conditions, temperature field, heat flow arrays and isotherms.Multiple consecutive simulations may be started externally (batch mode). Quick numerical method with optimization. Handy and rapid input due to an integrated pre-processor. ![]()
