The Most Frequently Occurring Problems

When attempting to perform certain actions, you are prompted to insert the FluidSIM CD.

FluidSIM cannot find certain installation directories on the hard disk. Probably not all of the software components were loaded at the time of installation. Either insert the CD or reinstall the missing software components.

Component cannot be moved or deleted.

Make sure that you are in the Edit Mode (); components can only be moved or deleted in the Edit Mode.

Components cannot be dragged onto the drawing area.

Make sure that you are in the Edit Mode.

Components cannot be moved or deleted in the Edit Mode.

Make sure that you have selected a component and not a component connection.

A line cannot be drawn between two connections.

Make sure to check the following points:

1.       FluidSIM is in the Edit Mode.

2.       No other connections are selected.

3.       Both connections do not have a blind plug.

4.       Both connections are of the same type.

The parameters of a component cannot be changed.

Make sure that FluidSIM is in the Edit Mode or that the simulation has been paused ().

The hard disk is running non-stop and the simulation is going slowly.

There is not enough memory available. A workaround is to quit other running applications or to quit Microsoft Windows © and restart the computer.

Already drawn lines, which are reported to be superimposed, cannot be found.

Press the Del key immediately after accepting the message; then draw a new line.

FluidSIM does not behave normally.

Exit both FluidSIM and Microsoft Windows ©, and then restart Microsoft Windows © and FluidSIM.

You are getting negative values for pressure.

Negative values for pressure mean that from a physical standpoint, the power supply unit is not providing the necessary output. Often, the reason is that there is a too high tensile load on a cylinder. In reality this situation can lead to different reactions, depending on apparent loads and the power supply unit involved. For this reason FluidSIM simply indicates a negative pressure value.

The pressure drop on a pressure relief valve is higher than its preset targeted nominal value.

There is really no mistake here: A pressure relief valve has a preset nominal pressure threshold, which is related to a certain pressure flow. If the flow should increase beyond this value, a larger pressure drop will occur, according to the resistance characteristics of the valve. The pressure relief valve is also not in the position to guarantee a certain pressure in all circumstances.

Components cannot be marked.

Please ensure that the option Protect Text Componentsis not activated and that the edit mode for the applicable drawing layer is activated.

Certain editing functions are not available in the context menu.

The context menu contains a practical subset of possible editing functions. Probably the operation that you would like to utilize applies only to one component at a time; if this is the case check to see that only one component is selected.

There is no pressure drop in the circuit, although a T-connection is apparently open.

T-connections are considered to be different from other connections: As an aid in drawing, they must not be provided with blind plugs because they are automatically closed if no line is connected.

The simulation time runs irregularly, although the slow-motion factor has been set to 1:1, and “Keep real-time” has been activated.

Both a complex circuit diagram and a slow computer could be reasons for the inability of FluidSIM to guarantee adherence to real-time.

At certain connections arrows for the flow direction are not displayed. The option Display Flow Direction has been activated.

The arrows only appear when a connection actual has a flow passing through it. This situation is not to be confused with a high pressure at a connection.

The animation is not repeated, although the “Loop” option has been activated.

The “Loop” option only applies to an animation that is not contained in part of a presentation.

FluidSIM is not behaving as expected, and you have already exited Microsoft Windows © and started FluidSIM new again many times.

Please uninstall FluidSIM and run a new installation.

Paste is not available from the menu, although a Copy operation has already taken place.

Only selected objects can be copied to the clipboard. If no objects are selected, only the picture will be copied to the clipboard.

No educational film will start playing.

Video playback requires appropriate hardware and software. Furthermore, FluidSIM needs to access the movie files. To ensure this, the FluidSIM-CD-ROM needs to be present in the drive or the video files need to have been copied to the hard disk during the installation.

The student version of FluidSIM is being loaded each time you start, although you have purchased the full version.

The FluidSIM CD contains both the student version and the full version of FluidSIM. During the installation procedure you are asked whether the full version or the student version shall be installed.

The mouse cursor is not switching as described, especially on top of connections.

Make sure that the option Large Mouse Cursor has not been activated. The large mouse cursor is designed to be used with a projector; here the switching of the mouse cursor is undesirable.

DXF Export... is not available from the menu.

Make sure that you are in the Edit Mode and that the window is not empty.

The text that was exported using the DXF filter does not appear as it did in FluidSIM.

The DXF format does not sufficiently support textual objects. I.e., CAD programs may not possess the ability to translate all fonts, font attributes, font colors, and special symbols.
