Method 1: Change Language During Program Startup

1. Close any open FluidSim projects.
2. Restart FluidSim.
3. Look for a small language selection dialog that sometimes appears before the main workspace loads (typically right after the splash screen).
4. Select your desired language (e.g., English, German, French, Spanish).
5. Click OK – the interface will reload in the new language.

Note: If this dialog doesn't appear automatically, your software version may have it disabled by default. Proceed to Method 2.

Advanced: Scripting and automation considerations

• If you automate generation or modification of FluidSIM files (e.g., batch creation of circuits), prefer machine-readable fields (component IDs, numeric parameters) rather than UI strings, since visible labels may differ by language.
• For custom libraries or components that include language-specific display names, consider adding metadata or multilingual name fields within your library files if the software supports it.

Using OS locale and user settings

If FluidSIM relies on the Windows locale:

• On Windows, FluidSIM may auto-select language based on the “Region & language” or display language settings in Settings → Time & language → Language.
• Changing the Windows display language or adding a preferred language can affect FluidSIM’s initial language on first launch, especially if no language has been explicitly set in program preferences.
• After changing the OS language, either log out and back in or restart the machine, then launch FluidSIM.

Caveat:

• Changing the OS display language affects all applications and is not recommended solely to affect one program unless acceptable for the user.

Part 4: Method 3 – The Registry Edit (Advanced Users Only)

Warning: Incorrectly editing the Windows Registry can break software or your OS. Only attempt this if you have administrator rights and have backed up your registry. Method 1: Change Language During Program Startup

Some legacy versions (FluidSIM 3 and early 4) store the language in the Windows Registry.

1. Press Windows + R, type regedit, and press Enter.
2. Navigate to: HKEY_CURRENT_USER\Software\Festo Didactic\FluidSIM\
3. Look for a key named Language, LangID, or Locale.
4. Double-click it and change the value:
   • 1033 = English (US)
   • 1031 = German
   • 1034 = Spanish
   • 1036 = French
   • 1040 = Italian
5. Close Regedit and restart FluidSIM.

Impact on files, templates, and symbols

• Circuit files (.fds, .fls, or version-specific formats) are primarily data-based and not language-dependent. Opening a file in a different language installation should preserve circuit content and parameter values.
• Text labels, comments, and custom template names embedded in diagrams remain as authored and will not be auto-translated. If you need translated diagrams, export text elements and translate them manually.
• Library component names shown in palettes may change according to UI language; underlying component IDs remain the same, so circuit behavior is unaffected.
• When sharing files across teams using different languages, agree on conventions for component naming, annotations, and templates to avoid confusion.

What Users Like (👍)

• Very easy – No digging through settings menus. Either a dedicated launcher or separate shortcuts.
• Reliable – Language change applies to all menus, component labels, simulation messages, and help files.
• No registry editing – Clean, portable-like behavior.

4. From the language dropdown, select the desired language (e.g., English, German, Spanish, French).
5. Apply or OK the change.
6. Restart FluidSIM when prompted (a restart is commonly required to reload UI resources).
