In the new version of REX/PSI Next Generation, significant changes and improvements have been made compared to the REX/PSI Classic version, which considerably enhance both user-friendliness and functionality. The following points describe the key differences in detail:

One of the most noticeable innovations in REX/PSI Next Generation is the fully redesigned graphical user interface. All graphical elements and dialogues have been completely reworked to provide a more modern and user-friendly experience.

• Individually customizable toolbar: Users can now configure and adjust the toolbar according to their specific needs, enabling quicker access to frequently used functions.
• Customizable user diagrams and visualizations: The presentation of diagrams and graphical visualizations is fully customizable in the new version, allowing users to tailor the display to meet their specific requirements and preferences.

Unlike the Classic version, a process in REX/PSI Next Generation is now presented in a tree structure. This new arrangement offers a clearer visualization and simplifies navigation through the individual process steps. The process is divided into the following components:

• Screw
  • Mech. Features
  • Sections / shearing and mixing parts / non-return valves
  • Internal cooling
• Barrel
  • Heating zones
  • Grooved bushing
• Hopper
• Process parameters
• Calculation settings
• Material
  • Polymer / mixture
• Data sheets
• Variation
• Scale up settings
• REX3D settings

The tree structure ensures that the individual components are better organized and more accessible, significantly facilitating the editing and review of processes.

Another major difference from the Classic version is the modernization of the file structure. Simulation processes are now saved in specialized file formats to efficiently consolidate all process-relevant information and results:

• REX: Simulation processes are saved in a *.rpro file .
• PSI: Simulation processes are stored in a *.ppro file .

These new file formats enable better data structuring and management, which is especially beneficial for complex simulations.

A significant upgrade in the new version is the comprehensive Variations Manager. This feature allows users to vary and simulate processes in all possible configurations. It opens up numerous possibilities for testing and optimization by allowing users to experiment with different parameters and combinations without altering the original process.

The results and reports customization in REX/PSI Next Generation has also been significantly improved. Users can now fully adjust the output results and long-term reports to suit their needs. This flexibility allows for the creation of specific report formats tailored to different use cases, improving the clarity and traceability of results.

Compared to the Classic version, REX/PSI Next Generation offers a range of important enhancements and new features. Along with the modern, customizable user interface and the tree-structured process layout, the new version stands out due to the expanded Variations Manager and flexible result visualization. The modernized file structure further simplifies the management of simulation processes, providing better organization and transparency. These innovations make REX/PSI Next Generation a powerful tool that meets the demands of modern simulation processes at a high level.
