      FluidFlow - Network License Speed Issues

      Resolve FluidFlow network license speed issues by optimizing network, antivirus, and local installation settings.

      If your FluidFlow application is experiencing speed issues, there are several possible causes and remedies.


      1. Network Performance (VPN/LAN/WAN)

      The speed of your network can impact FluidFlow performance.

      • Check for possible bottlenecks.
      • Consult your Network Administrator to review Event Logs at the times the issues occur.



      2. Antivirus Scanning PSFF.EXE

      Some antivirus software checks PSFF.EXE every time it starts, causing delays.

      Solution:

      Add both of the following to your antivirus Exceptions list:

      • FluidFlow application folder (where PSFF.EXE resides)
      • FluidFlow Public Documents folder (if used)


      Example for AVG:

      Settings → General → Exceptions

      Note: Replace the example paths with your actual server paths.

       



      3. Local Installation Pointing to Server Data

      If you prefer not to change antivirus settings:

      1. Install FluidFlow locally on your PC.
      2. Replace the local PSFF.INI with the version from your server installation.


      Example configuration:

      [Options]
      NetworkAccessFolder=\\\\[YourServername]\\[Path]\\FluidFlow3
      DataFolder=\\\\[YourServername]\\[Path]\\FluidFlow3\\Data
      PreferencesFolder=\\\\[YourServername]\\[Path]\\FluidFlow3\\Preferences

      Note: The PSFF.INI file is created automatically in the FluidFlow installation folder on your PC.



      4. Reducing DATA Transfer During Model Calculations

      When solving a model, FluidFlow checks for updated equipment data and fluid properties, transferring several MB over the network.

      Option A – Local DATA Folder with Network License

      [Options]
      NetworkAccessFolder=\\\\[YourServername]\\[Path]\\FluidFlow3
      DataFolder=C:\\Users\\Public\\Documents\\Flite\\FluidFlow3\\Data
      PreferencesFolder=C:\\Users\\Public\\Documents\\Flite\\FluidFlow3\\Preferences


      • Update NetworkAccessFolder to match your server’s PSFF.INI.

       

       

      Option B – Copy Server DATA Folder Locally

      • Keep executable and license file on the server.
      • Copy the DATA folder locally.
      • Point to this folder via the ‘Database | Connections….’ menu item.




      Important:

      • Users will not share DATA folders in either option A or B.
      • To merge records from multiple users, use the Save/Load functionality in the Database Editors.
