Basic Functions & Program Operation

This guide provides an overview of the core operational logic, navigation, and data input methods within Design Atlas 2026.

1. Starting the Program & Module Selection

When the program starts, the Module Selection appears immediately. You can find the correct module for your task in several ways:

  • Text Search: Enter keywords or standard IDs (e.g., "1092" for flanges) to filter the 500+ modules.
  • Quick Start: Navigate through categories and symbols to find the task-specific module.

2. Core Concepts & Terminology

Understanding the following terms is essential for efficient program operation:

  • Module: A standalone program dealing with a specific subject (e.g., "Cylindrical shells under internal pressure").
  • Module Package: A combination of several modules that exchange related variables dynamically.
  • Event: Triggered when you enter or change a value, starting an immediate calculation within the module or package.
  • Statement: Every variable requires an input. If a feature (like a nozzle) does not exist, you must enter "0" to make a definitive statement.

3. Data Input & The Equation Solver

Design Atlas uses a unique Equation Solver that allows for flexible, bidirectional design.

  • Value Colors: Entered values are displayed in black, while calculated results appear in blue.
  • Overwriting Results: You can overwrite a calculated value (blue). If the equation has more than two variables, the "Clear Variable" window opens, allowing you to choose which input value should be recalculated.
  • Expert Mode: When activated in the settings, this mode allows you to overwrite calculated or database values to compute backwards to a previous input value.

4. Advanced Input Techniques

  • Value Ranges: Enter ranges directly (e.g., "1 to 4"). You can then use a slider or arrow keys to vary the value and see instant results for all dependent variables.
  • Parameter Studies: Perform 2D studies directly in the mask by entering a sequence (e.g., 1, 1.1...2). The program automatically computes all dependent steps.
  • Definition Files: Frequently used variables can be saved as a definition file. When activated, these variables are pre-allocated every time the module starts.

5. Unit Conversion System

The software features a fully integrated conversion engine: * Direct Input: You can enter a value followed by a unit (e.g., "100psi"). The program converts it immediately to the displayed unit. * Toggling Units: Switch the displayed unit by clicking it on the mask. * Global Settings: The entire unit system (SI vs. US units) can be set globally via Options > Settings > Appearance.

6. Drag & Drop Module Connection

To avoid entering data multiple times, you can link variables between different modules: * Workflow: Drag the tab of one module (e.g., B1) and drop it onto the input mask of another (e.g., B9). * Dynamic Update: Once connected, changing a value in one module automatically updates the linked values in the other.

7. Help & Information Systems

  • InfoBrowser: Displays variable-specific information, program messages, and a "Variable Monitor" to track changes.
  • Question Marks: Clicking the blue/white question marks next to a variable opens detailed technical data in the InfoBrowser.
  • LV Consultant: Accessed via the "Help" menu, this allows an engineer to connect to your PC via TeamViewer to solve complex calculation questions.

💡 Pro-Tip: Canceling Calculations

If a complex iteration is taking too long, hold down the ESC key until the program stops the calculation and allows for new input.
