A software package that analyses how turbulent and laminar flow affects products such as aeroplanes, cars and boats, should make life easier for design engineers.
Unusually, both types of flow can be studied at the same time as part of the same model. And there is no need for users to have the detailed knowledge of turbulence theory to get the best results, as was needed with traditional fluid flow software.
The software uses computational fluid dynamics technology to show where and how the different types of flow act within a computer model.
Comparison of the results from the program with actual lab test results have shown that it works to a high degree of accuracy.
The software is available as an add-on to any Algor 2D or 3D steady-state and transient fluid flow analysis packages.

* When you need to get to the bottom of a problem, the hardest thing is often knowing just where to start in analysing the situation. Or, as software company Invention Machines puts it: `Constructing a problem statement is approximately 80% of the problem solving process.’
The danger is that errors can creep into this problem statement and engineers can end up solving the wrong problem.
To avoid timewasting, TechOptimizer steers engineers through the formulation of the problem statement. It integrates functional analysis, feature transfer and trimming technique to get a clear and simple picture of what is at issue.
Having got to the crux of the matter, another Invention Machines package, IM Lab, will even help engineers through the remaining 20% of the problem- working out the solution.

Software keeps tabs on network equipment
A new class of software is now available for monitoring and controlling a large range of different types of equipment in different locations. It could be used, for example, in test rig monitoring, environmental monitoring or production cell logging.
The software, Windmill ELS, runs under Windows NT or 95, logs data from instruments and sensors, monitors alarms and implements control loops locally. It displays the data in realtime and regularly updates a central archive. This means that if one part of the network fails, everything else can keep going without losing information.
Windmill ELS takes the addition of new sensors or instruments, or changes in parameters, in its stride without the need to shut down operations.
It has drivers for hundreds of instruments from different manufacturers.

* Fluke, the electronic test tools specialist, has introduced a data logging package that extends the problem solving capabilities of its 41 and 41B harmonics analysers.
FlukeView 41 for Windows will record critical data for up to three days. The data can be used later for the generation of reports in graphical or numerical formats.
