Modular Structure

Prefabricated modules are combined with new applications instead of creating a new program for every new task, which enables us to realize our customers' requirements very quickly. The single module is a specialist, standardized in construction and tested thoroughly. LV offers modules for the following calculations:

• Strength of pressure vessels and piping
• Process engineering equipment such as heat exchangers, condensers and separators
• Properties of individual substances or mixtures and of their phase equilibria.

All modules are structured under a uniform operating platform. Input is made in input masks on modular level and the procedure is always identical.

Optimizing of calculation is another most important topic regarding today's competition. The LGO module developed by LV is unique because of its internal optimizer which can be controlled freely. It shows how to design a heat exchanger, vessel, nozzle or piping network competitively. Like all the LV modules, the LGO module can be combined with any other LV modules.

Customers' specific modules

Due to the modular structure, customers' specific calculation attachments can be considered and integrated into a program package very easily. There are no difficulties to apply company standards or design formulas based on own measurings while general calculation procedures are used.

Data input

The mathematical convention for the modules is based on a numeric equation solver. This means, that the data can be entered in any order whatsoever. The calculation starts immediately after the input and proceeds while the input is continued until the problem is finally solved. This applies to single units as well as to combined processes.

This procedure allows an optimization of any arbitrary target variable which leads to unlimited possibilities of mathematical observation.

The most important equations are displayed directly on the screen and the variables can be entered into the formulas directly.

Values can be entered into the input fields in any unit. After having activated "Conversion of units" by pressing the key the input value is converted to various units which are displayed in a list. The value of any listed unit can be edited afterwards. It is converted to the other units immediately.

Interfaces to other programs

The modules of the ATLAS program system can be integrated into object-oriented applications such as MS Excel, CAD or they can be integrated into programs which were developed in object-oriented programming languages (e.g. Java, VBA and so on).

For this purpose, the ATLAS program system provides properties, procedures and results which can be called in other (client) programs. Due to this technique it is possible to incorporate LV programs into other programs. Special calculations are performed quickly and exactly by the LV module and the result is displayed directly in the offer letter.

Based on this technique LV offers completely configurated interfaces for MS-Excel, for the CAD programs SolidEdge and AutoCad as well as for the process simulation program Design II by WinSim.
