SimFlow Installation

Installation on Windows

SimFlow software supports the Microsoft Windows operating system and is provided as an automatic installation package. Download SimFlow and follow the automatic installation procedure.

Installation on Linux

The software is provided as an automatic installation package for 64-bit architecture. The installation procedure is presented below due to additional actions required from Linux users. Note that this procedure might be slightly different depending on your distribution.

Installation procedure

  • Download the latest version of SimFlow
  • Make file execution available. Linux OS usually sets packages downloaded from the Internet as unable to run. You can change it in two ways:
    • Terminal:
      • Open a terminal window and go to your download directory:
        cd <Download Dir>
      • Make the installation file executable by typing:
        chmod a+x simFlow-<version>-Linux-<architecture>-Install
    • System:
      • Open folder with the installation package
      • Click right mouse button over the installation file and choose Properties.

      • Go to the Permissions tab and check "Allow executing file as program"
  • Run the installation by double-clicking on the installer or run it from the console:
  • If you want to install in a root directory, run the installation as a root:
    sudo ./simFlow-<version>-Linux-<architecture>-Install
  • Follow the on-screen installation step-by-step procedure.
  • After successful installation SimFlow should run automatically.

If this is your first SimFlow installation, then the program will automatically search for OpenFOAM and ParaView software in default locations on your system. If those installations are not found, then before launching your first case the The "Advanced Configuration" window will pop out. You will be obligated to configure SimFlow manually. A detailed explanation of how to configure SimFlow can be found in the following section.

OpenFOAM and ParaView on Linux

The installation package for Linux includes only SimFlow itself. To run simulations you need to install the OpenFOAM (the computational backend for SimFlow) from one of the official distributions:

To be able to do advanced postprocessing it is recommended to install the ParaView software as well:

In order to tell SimFlow where to find OpenFOAM/ParaView you will need to edit settings just before running your first case. You can learn more about how to do this here.

Linux Installer - Console Mode

In some cases, it might be required to install SimFlow on a machine without access to the graphics context - non-GUI mode.

Also, if your system is missing graphics libraries used by the installer (the Installer window doesn’t open) you can try using the console mode. SimFlow uses its own libraries, and thus, it should be able to run under your system despite the fact that the installer could not.

To uninstall SimFlow using the console mode use the same options listed for the installer

Step-by-Step Installation

In order to run the installer in console mode:

  1. Change the directory to the location of the installer, e.g.,
    cd ~/Downloads
  2. Run the installer in console mode
    ./simFlow-4.0-Linux-x86_64-Install --mode Console
  3. Follow instructions from the console.
    You will have to type the installation directory manually.
    (please note that the installer will append the "simFlow" directory automatically).

Single Line Command Execution

Alternatively, you can skip the step-by-step procedure and run the installation in silent mode. In this case, you can run the installer and provide the installation directory as a single command. This approach is well suited if SimFlow installation should be placed under some sort of scripting automation.

To run the installer in silent mode and provide an install directory use the following command:

./simFlow-4.0-Linux-x86_64-Install --mode silent --prefix /path/to/install/location
