General

What are the system requirements for FluidSIM?

FluidSIM runs under all versions of Windows from Windows XP, including Windows 10 (both 32-bit and 64-bit). We recommend a dual processor and at least 2 GB of RAM.

How can the Xbox controller be used to control the simulation?

In FluidSIM it is possible to adjust component parameters during simulation (e.g. for a throttle). If you move the mouse cursor over an adjustable component during simulation, it turns into a slider symbol. Clicking with the left mouse button lets you adjust the parameters in the dialog, which is then shown.

Alternative to using the mouse, component parameters can be adjusted with the help of a connected game controller like the Microsoft Xbox controller. To do so, open up the property dialog of the component you want to control while in edit mode.

Click on the button in the „Variable“ column of the component parameters. An extended dialog for the “Variable assignment” will open up. Additional to the “Variable access”, you can see the region “Controller assignment”. Left click the textbox with the label “Axis” and move the desired axis of the controller, to have FluidSIM assign the correct axis to control the parameter. If you prefer a stepwise control, you can switch to “Stepwise Control (-/+)” and assign one axis each for + and -. Please note, that in contrast to the direct control, it is relevant in which direction you move the controller, when assigning an axis.

It is also possible to press a controller button instead of an axis. Controlling a parameter with a continuous value, using a button only makes sense when selecting stepwise control mode.

Using the input for “Dead-zone” allows for selecting the minimal axis displacement before a signal is triggered. This prevents an unwanted change in parameter by the slightest movements or backlash of the controller.

In the “Range” section of the dialog, you can adjust how controller position and parameter values correlate. You can, for example, restrict the range which can be controlled with the game controller. The line can be changed interactively using the mouse. It is also possible to use the fields below the diagram to define two points, which define the line. Since most game controllers return back to neutral state when released, this setting allows for selecting the parameter value in position at rest.

Start the simulation and move the assigned controller axis. The controlled parameter gets adjusted. By using different axis you can control different parameters of a single or multiple components at the same time, which would not be possible by using the mouse only.

Licensing

What types of licensing available?

Three variants are available:

  1. Product activation (similar to Windows activation)
    During installation, you enter your individual product ID. After that the license is permanently connected to a specific computer. If you want to transfer the license to another PC later, you can uninstall FluidSIM and release the license again. For this variant, you need an Internet connection at installation time. Alternatively the necessary activation code can be obtained by phone. A phone number is then displayed in the setup.

  2. USB license key (Floating License)
    The license connector can be connected locally or on a network server. You can run FluidSIM from any PC in the network as often as licenses are programmed on the stick. We recommend this licensing option for more than two or three licenses and if you want to use FluidSIM on different PCs.

  3. Remote license (Internet cloud)
    This version works like the floating license with USB stick. So you can use FluidSIM on any PC up to the maximum number of licenses. The license count is not done in the local network via a USB stick, but via the Internet. Thus, an Internet connection is required during the entire FluidSIM session. This licensing is useful when FluidSIM is running at different locations on different PCs. A management tool enables, for example, a teacher to manage password-protected access, to temporarily allow students the use of FluidSIM.

Demo version

I didn't get any activation code for the FluidSIM 5 demo.

There are several possible reasons that you didn’t receive the activation mail:

  • Please check your spam-folder at your e-mail provider. Maybe our activation mail was erroneously classified as spam.

  • Please make sure, that you have the latest demo version available. You can check the version of your FluidSIM demo on the splash screen, that is shown behind the dialogue to enter the activation code, when you launch the demo executable. In the lower left the version number should say “5.5 02/09/2017”. If you have an earlier version, please download the current version from here.

  • To activate the demo version you need a working internet connection. If you use a personal firewall, allow the FluidSIM demo to connect to the internet. If you are connected to the internet via a proxy server, an authentication dialog may appear after pressing “Register”. Type in here user name and password as you would when using your internet browser.

I have the demo version installed under Windows 8.1, but I cannot find it now.

The icon of the FluidSIM demo should be displayed in the list of all apps. Either switch to the Metro interface and scroll down to display all apps, or use the integrated search. In the Metro interface, simply enter “FluidSIM”, and the link to the FluidSIM demo should appear as a search result.

Normally, the demo will be installed in the folder: “C:\Program Files (x86)\Didactic\FluidSIM5 Demo”. The “bin” directory contains the file “FluidSIM5Demo.exe”. Double-click on this file to run the demo.

I cannot register the FluidSIM demo version. It always appears the error message "No Internet connection available."

The FluidSIM demo version requires Internet access to the Internet address www.artsystems.de for registering and executing. Please make sure that access to this address is not be blocked by a firewall or proxy. If necessary, contact your system administrator to allow you access to this website.

When requesting the activation code or the start of the demo, a dialog "proxy access" appears. What should I do?

The FluidSIM demo requires Internet access. The proxy dialog comes up, because FluidSIM could not directly access the Internet and has recognized that a proxy is used to access the Internet in your company network.

Please enter the same credentials you use for your Internet browser.

Installation

Can FluidSIM be installed without user interaction (silent mode)?

Both the setup and the update can be executed without user interaction. However, during the first installation, depending on the type of licensing, USB drivers have to be installed previously. For further information, please contact our support.

The update can be executed with the command line parameter /q for a silent installation. All installed technologies are updated at the same time.

Didactics material

FluidSIM dows not show the educational films. Instead of the video only a box with a red X appears.

The educational films must have been installed during the installation of FluidSIM, so they can be displayed in FluidSIM. Presumably this was not done with your installation. You can verify this by checking if the directory

C:\Program Files (x86)\Didactic\FluidSIM5-P\dida\pneu\en\

or

C:\Program Files (x86)\Didactic\FluidSIM5-H\dida\hyd\en\

contains files with the extension .swf for Shockwave Flash. If only one pneu.bin or hyd.bin file can be found, the educational films were not installed.

If the educational films are not installed, you need an installation DVD of FluidSIM to install the movies later. Just run the setup of FluidSIM from the DVD. The installation wizard will recognize that FluidSIM is already installed. You can then select that individual components such as movies, animations, etc. are to be installed. Simply follow the instructions of the installation wizard.

Important note: The installation of additional components resets FluidSIM to the DVD version. Please re-install the latest update, if necessary.

When playing the educational films FluidSIM crashes.

To play back the educational films the Flash player is used. This is no longer compatible since a specific Windows update. The bug has been fixed since version 5.2 of FluidSIM. Install the latest update if you are affected by the problem.
