Software for heat transfer and ground heat

HEAT2 - Heat transfer in two dimensions

What’s new in HEAT2 version 8

For detailed description please see  Update manual HEAT2 8 (PDF), 2011 

The following list shows a summary of new features:

Polygon tool added
A new polygon tool allows easy input of sloped edges and boundaries.

Bitmap drawing and filling

A new bitmap editor is added where input can be made using a variety of graphical tools, such as ellipses, rounded rectangles, brushes, pencils, fill, etc.

A bitmap or jpeg can be imported and areas can easily be filled with different materials. Very complex geometries can be given in a short time using this option.

It is also possible to draw any geometry in an external cad-program or paint-program using pre-defined colors (RGB) matching the colors in the HEAT2 material list, and then export/import a bmp/jpg and scan and create the geometry in HEAT2.

Increased sizes for data fields

Many data fields have been increased in sizes. The maximum number of numerical nodes has been increased from 490,000 (700·700) to 4,000,000 (2,000·2,000).


Hundreds of minor improvements are made. The most important are shown below:

· A new editor for giving lengths for drawn rectangles in the pre-processor has been added.

· Dialog added to change and set default material file.

· The distance from a reference point to the mouse cursor is now shown in the pre-processor. This may be useful for e.g. checking the width of a sloping material.

· The chart for temperatures/heat (menu item Output/Temperature along line boundaries) has been updated. The chart editor is also updated.

· The Solve-window (F9 and F10) now shows the sum of all positive boundary flows (earlier the sum of all absolute boundary flows was shown).

· Check for software updates added.

· New report generator with export to PDF, HTML, XLS, RTF, TXT, XML, QRP, QRX.

· Now also adapted for Windows 7 and Vista.


Enhancements in post-processing:

· Faster drawing/updating

· Mouse cursor sometimes “froze” for a small moment in earlier versions. This has been fixed.
