Project tree

Understanding the project tree in EFFECTS

The project tree is a crucial component of the EFFECTS software user interface, designed to facilitate easy navigation and organisation of various project elements. This hierarchical structure organises all user input and project components, allowing users to manage their data efficiently. The project tree contains a series of tree nodes as seen in the figure below:

The top node, called EFFECTS Project, is a typical placeholder for all user input. The name of this node reflects the current project filename and can only be changed through the "File - Save As…" option.

The hierarchical tree view under the top node (EFFECTS Project) illustrates the input and various elements of the project in a structured manner. This hierarchical tree view provides a clear and organised way to access different components of the project, making navigation straightforward and intuitive.

Project tree components

The project tree comprises several key nodes and settings that users need to be familiar with including:

• Presentation settings: contain some typical settings to customise the appearance of the results, although the numerical results remain the same.

• Backgrounds: allow users to incorporate different background images or maps into their project, to aid with spatial analysis.

• Receivers: to define vulnerable areas that help analyse the effects of toxic or flammable clouds on exposed populations, as well as to define 3D congestion areas for explosion assessment of flammable clouds.

• Equipment: to define the location of process equipment such as storage tanks, pipe rupture, heat exchangers, reactors, etc. from which an accidental release occurs.

• Model tree: to define the loss of containment scenario that occurs within anequipment location.

• Comparison set: to enable users to compare different scenarios or models within the same project. This feature is useful for conducting sensitivity analyses and optimising safety measures.

Navigating through the project tree

The project tree is designed to streamline the workflow within the EFFECTS software. By understanding and utilising each component effectively, users can manage their projects more efficiently, ensuring accurate and comprehensive modelling of accidental releases of hazardous chemical substances.

Some tips for effective use are as follows:

• Expand and collapse nodes: Click on the arrows next to each node to expand or collapse sections, making it easier to navigate through the project components.

• Right-click for options: Right-clicking on different nodes often provides additional options or shortcuts specific to that component.

• Organise your data: Use the hierarchical structure to logically organise your data, which will help in managing large and complex projects.

• Regular saves: Frequently save your project to avoid data loss, especially after making significant changes.

By following these guidelines, users can take full advantage of the project tree's capabilities, leading to more efficient and effective project management within the EFFECTS software.

Conclusion

The project tree in the EFFECTS software is an indispensable tool for navigating and managing the various elements of loss of containment modelling projects. Understanding its structure and functionality allows users to organise their data efficiently, customise their settings, and perform comprehensive analyses. This ensures accurate modelling of hazardous substance dispersion and enhances overall project management and safety.
