Description TEMP/W is a finite element program for geothermal analysis of problems varying from steady state thermal conduction to transient freeze-thaw. Phase changes (ice/water) take in to account latent heat and are controlled by an unfrozen water content function. Boundary conditions modelled: constant temperature and/or heat flux, transient temperature and/or heat flux as a function of time, relationships between air and ground surface temperature are defined by modified n-factor functions. Soil properties modelled: frozen and unfrozen volumetric heat capacity, volumetric water capacity, thermal conductivity as a function of temperature. TEMP/W computes total heat flux across user defined single or multiple sections. The results are displayed as contours, graphs and heat flow vectors. The changing freeze-thaw front can be plotted as a function of time. New features in 2007 version: Multiple analyses of similar or different types can be done in a single project file. Different solutions can be compared in the same file. Staged analyses can be done for construction sequencing with moving boundary conditions. Define boundary conditions and material properties by geometry region, rather than on the finite element mesh. Unstructured quadrilateral mesh with fine-tuning options. Interface elements can be added on lines to model soil-structure interactions, liners and geo-fabrics, cutoff walls and wick drains. Define a results graph on a geometry object (line, point, or region) or on a cut line or plane. Plot multiple results graphs together to compare data. Make a movie of analysis results to show how results change over time. Custom user add-in functions to define material property or boundary condition functions using internal solver data or external data held in Excel or any other .NET program. Examples with a detailed discussion on how to use and apply the relevant features and how to interpret the results. Fault-tolerant licensing on a wide area network. AIR/W can be linked to account for convective heat transfer in moving air. Full thermal, simplified thermal, and convective thermal models. Boundary conditions are preserved if you change the mesh. Time stepping setup and results saving scheme. Built-in sample soil property functions. Thermosyphon boundary conditions. A free evaluation version is available.
