WUFI® (Wärme und Feuchte instationär) is a software family which allows realistic calculation of the transient coupled one- and twodimensional heat and moisture transport in multi-layer building components exposed to natural weather.

It is based on the newest findings regarding vapour diffusion and liquid transport in building materials and has been validated by detailed comparison with measurements obtained in the laboratory and on IBP"s outdoor testing field.

Hygrothermics
Besides the thermal properties of a building component and their impact on heating losses, its hygric behaviour has to be considered, too. Permanently increased moisture content in the component may result in moisture damages. Elevated surface moisture levels in living rooms can lead to hygienic problems and health risks due to mould growth.

In addition, thermal and hygric behaviour of a building component are closely interrelated: an increased moisture content favours heat losses; the thermal situation affects moisture transport. Therefore, both have to be investigated together in their mutual interdependence; the research field of hygrothermics is dealing with these problems.

Out of Date: Glaser
The Glaser method as detailed in German standard DIN 4108 has been a common method to assess the moisture balance of a building component by considering vapour diffusion transport in its interior. However, this method does not allow for the capillary moisture transport in the component, nor for its sorption capacity, both of which reduce the risk of damage in case of condensation. Furthermore, since the method only considers steady-state transport under heavily simplified boundary conditions, it cannot reproduce individual short-term events or allow for rain and solar radiation. It is meant to provide a general assessment of the hygrothermal suitability of a component, not to produce a simulation of realistic heat and moisture conditions in a component exposed to the weather prevailing at its individual location.

Up to Date: WUFI
The menu-driven PC program WUFI (Wärme und Feuchte instationär - Transient Heat and Moisture), developed by IBP and validated using data derived from outdoor and laboratory tests, allows realistic calculation of the transient hygrothermal behaviour of multi-layer building components exposed to natural climate conditions.

WUFI is based on the newest findings regarding vapour diffusion and liquid transport in building materials.

WUFI only requires standard material properties and easy-to-determine moisture storage and liquid transport functions.

WUFI can use measured weather data - including driving rain and solar radiation - as boundary conditions, thus allowing realistic investigations on the behaviour of the component under exposure to natural weather.

WUFI can be used for assessing

• the drying time of masonry with trapped construction moisture
• the danger of interstitial condensation
• the influence of driving rain on exterior building components
• the effect of repair and retrofit measures
• the hygrothermal performance of roof and wall assemblies under unanticipated use or in different climate zones.

WUFI is a tool for developing and optimising building materials and components. For example, it was used as a development tool for the smart vapour retarder.

WUFI is directed at manufacturers of building products, consultants, designers, engineering offices and experts in the field of hygrothermics.

WUFI may be used as a teaching aid or advertising tool because of the instructive visualisation of its calculation results.

WUFI runs on PCs under NT4 (SP6), Windows 2000, Windows XP and Windows Vista. The comprehensive on-line help and documentation amounts to ca. 200 A4 pages. WUFI can be switched between six languages (German, English, Finnish, Polish, French, Norwegian). A free Research and Education version is available for download.
Proper application of WUFI requires experience in the field of hygrothermics and some basic knowledge in the use of numerical calculation methods.

UVLayout is a stand-alone application for the creation and editing of UV coordinates for 3D polymeshes and subdivision surfaces.

Used by professionals in the games and visual effects industries, by hobbyists of all ilks and by students, UVLayout"s unique approach gives texture artists the tools to produce high quality low distortion UVs in significantly less time than they would by traditional methods.

Using UVLayout could be described as the opposite of dress making; instead of cutting out a flat pattern and sewing that up to make clothing, in UVLayout the is cut into pieces that are then flattened out to make the pattern. These flattened UV shells are not just planar projections; a dynamics based algorithm is used to spread the UVs out, as you watch, so that there"s minimal stretching, compression or skewing of textures when they"re applied to the .

Some major features of UVLayout are:

• OBJ import and export
• Edge-loop Detection for quicker UV seam selection
• Symmetry Editing for faster flattening of symmetrical meshes
• Edge Straightening on shell boundaries and interiors
• Flattening Brushes for local tweaks of the automatically generated UVs
• Auto Packing of UV shells to minimize wasted texture space
• Auto Stacking of similar shells for shared texture space usage
• Subdivision Surface calculations based on limit surface shape
• Unlimited Undo of all editing functions
• Plugin Interface for integration into other applications

If you are looking for an easy to use, powerful and affordable schematic capture and printed circuit board design package that gets the job done, EAGLE is the number 1 choice!

CadSoft offers user friendly, powerful and affordable solutions for PCB design, including Schematic Capture, Board Layout, and Autorouter.

Take this Guided Tour and discover EAGLE. You will be surprised!

EAGLE provides a schematic editor, for designing circuit diagrams and a tightly integrated PCB layout editor, which automatically starts off with all of the components required by the schematic. Components are manually arranged on the board, with the help of coloured lines showing the eventual connections between pins that are required by the schematic, to aid in finding a placement that will allow the most efficient track layout.

It also provides a good autorouter, which once the components have been placed will attempt to automatically find an optimal track layout to make the electrical connections. It does not always manage to find a way of routing all the signals, although it permits manual routing of critical paths such as power and high frequency lines before letting the autorouter handle the other connections.

EAGLE is very popular with hobbyists because the free demo is able to create usable PCBs. (Free ECADs from some companies are crippled so that they won"t save or won"t print.) The only limitations of boards made with the EAGLE demo are: 2 copper layers; a maximum size of 80mm x 100mm (½ Eurocard)(~3in x ~4in). The demo versionof the schematic editor module can only create single-sheet schematics.

AlgoLab Raster to Vector Conversion Toolkit converts architect, mechanical and various technical drawings, maps and other types of line artwork including black and white graphics for books and journals from raster to vector formats. This means that a paper drawing can be scanned, line artwork automatically recognized and represented in a vector format that then can be imported to your CAD or drawing program.

Professionals in Cutting, Engraving, Sign Making and other CAD/CAM systems may want to take a very close look at Toolkit due to its ability to create fine lines and outlines. Toolkit has the unique special feature to refine curves. So with a proper choice of parameters a vectorized drawing composed of curves normally looks better than the original one.

Toolkit is also tailored to digitize drawings including mathematical graphs for further use in MS Excel, Mathematica, Lotus 1-2-3 and other mathematical programs.

Toolkit is designed to provide quality of high-end products. Even those who have one of such high-end products may certainly find that at least for some kind of drawings Toolkit provides better quality of the output vector files. So it is reasonable to have Toolkit available.
