Parametric Study Tool
The Parametric Study tool enables rapid and in-depth simulation analysis, allowing users to explore a wide range of input parameters efficiently. By systematically varying inputs, the tool helps identify critical factors affecting system performance, enhancing sensitivity analysis and optimization. Engineers can gain clear insights through graphical trends, even in cases where traditional goal-seeking methods struggle. This approach facilitates better decision-making by providing visual justifications for key trade-offs, such as cost versus performance.
With its ability to generate full scenario analyses and optimize operating conditions, the tool empowers users to make data-driven decisions confidently. Whether pinpointing essential calibration components or presenting compelling reports for stakeholders, this solution offers a streamlined, intuitive approach to simulation analysis-enhancing efficiency, accuracy, and overall system success.

Graph Annotations
Graph Annotations is a new feature designed to enhance modeling workflows by allowing users to add auto-updating graphs directly to their Workspace. These graphs provide instant insights by visually comparing model results without requiring users to navigate elsewhere. Fully resizable, movable, and easily hidden, they function like Color Map layers, updating automatically based on Output data. By bringing the capabilities of the Graph Results tab to the Workspace, this provides a streamlined approach to reviewing key data, improving efficiency and decision-making.
Creating a Workspace Graph is simple-users can add a Graph Annotation from the Toolbox, select a desired Description, and configure parameters. Once set, the graph refreshes automatically with new Output data, ensuring up-to-date insights. This enhancement makes analyzing complex scenarios more intuitive and user-friendly, offering a smarter, more visual way to interact with model results.

Scenario Comparison Layer
The Scenario Comparison Layer enhances clarity in scenario analysis by visually highlighting differences between the current scenario and a selected comparison scenario, whether explicitly chosen or related by one degree (Parent, Sibling, or Child). Objects with differences are color-coded on the Workspace, allowing users to quickly identify differences between the scenarios. Each modified object provides an easy way to inspect specific parameter and value differences through the object labels and the Inspection Window. This update delivers the capabilities of the Scenario Comparison Tool through a much more visually appealing and intuitive layer, streamlining the analysis process and improving user efficiency in interpreting complex models.

Cross-App Heat Exchanger Thermal Link
The new Cross-App Heat Exchanger Thermal Link feature in Fathom and Arrow streamlines the thermal analysis of liquid-gas heat exchangers by allowing direct thermal connections between heat exchanger junctions in gas (Arrow) and liquid (Fathom) systems. This integration enables both applications to run simultaneously until a converged solution is reached, eliminating the need for manual iterations. By automating this process, users can significantly reduce errors, complexity, and the time spent on iterative adjustments.
Previously, modeling heat exchangers in mixed gas-liquid systems required users to manually tweak inputs and rerun simulations, making the process both time-consuming and prone to errors. With this new feature, heat exchangers can now be modeled more seamlessly and efficiently, providing a faster and more accurate workflow. This enhancement allows engineers to focus on optimizing their systems rather than adjusting inputs, ultimately improving productivity and system performance.

Enhanced Heat Exchanger Modeling
Estimated Overall Heat Transfer Coefficient and Vary Overall Heat Transfer Coefficient With Flow heat exchanger models provide new options for representing how heat transfer performance changes with flow rate. For models using an overall heat transfer coefficient (U), users can now define a U vs. flow rate curve directly - offering a clear way to account for performance variation across operating conditions. Alternatively, an estimated variable U option lets users specify U at a single flow rate. Behind the scenes, the system calculates how U changes with flow based on that input and the heat exchanger's geometry. This delivers a more realistic and flexible approach to modeling flow-dependent heat transfer without requiring extensive input data.

Other Notable Features
- Design Alert Layer - Real-time visualization for efficient model analysis.
The Design Alert Layer is a new feature designed to enhance model performance visualization and analysis. It provides color-coded indicators on the Workspace to highlight objects that have violated Design Alerts. Each affected object is labeled with the specific condition and evaluated value, eliminating the need for manual checks. This feature streamlines model analysis by identifying and highlighting areas of the Workspace that are exceeding user-set system requirements. Multiple Design Alerts can be viewed at a single time, helping to quickly identify locations of the model that need attention and review for a range of different system conditions.

- Control Valve Sizing Tool - Automating control valve conversion for efficiency.
Control valves junctions are commonly used as a design tool for sizing passive flow devices that rely on hydraulic resistance to control flow distribution within a system. Typically, converting control valves to equivalent orifices or valves requires iterative adjustments and multiple simulation runs-consuming valuable engineering time. However, the new Control Valve Sizing Tool streamlines this workflow by automating control valve conversion, allowing engineers to efficiently select multiple control valves and instantly transform them into equivalent orifices or valves with just a few clicks.

- Improved PCF Importing - Enhanced PCF import control and accuracy.
The Improved PCF Importing feature provides greater control over how PCF file elements are brought into the Workspace. Multiple PCF files can now be imported at once, streamlining batch workflows. Welded junctions are automatically handled using zero-length connectors, and pipe length units can be adjusted directly in the import preview. A new window also makes it easier to define pipe materials during import, reducing the need for post-import editing.

- Global Junction Morph - Convert multiple junctions from one type to another.
The new Global Junction Morph feature streamlines model updates by allowing you to convert multiple junctions of one type to another-all at once. Ideal for refining model details or adapting to design changes, this tool delivers a faster, more consistent way to restructure your system and save valuable engineering time.
