1.7. Limitations

  • While a remote client can connect to up to 6 different remote Fluent server sessions at once, a single server can only have one remote client connected at a time.

  • You cannot rename or delete graphics objects from the remote client

  • (Windows only) Starting the server is not supported if Ansys Fluent is launched with either the -g or -gu options from the command line.

  • If a calculation is started on the server-side, the beginning and end of the transcript will be missing on the client-side.

  • For any actions sent from the Remote Visualization Client to the server (initialization, starting calculation, text commands using Send Command to Server), text prompts are automatically answered. For example, if the question is A report file already exists with this name in the current directory. Create a new report file? Ansys Fluent automatically answers yes to this question and begins calculating.

  • Do not start calculations from the Send Command... option on the client side- they must be started using the GUI on the client.

  • Plot properties (that is, axis and curve properties) are not transferred to the Remote Visualization Client. Residuals are always plotted on a logarithmic scale and other plots are on a standard scale.

  • Report plots cannot be created or edited from the Remote Visualization Client.

  • (Linux only) If a Remote Visualization Client is started from a server, the client will close when the server that launched it is closed.

  • Custom mesh colors can only be set in the server, although they can still be displayed in the client. However, if the mesh colors include realistic materials, they cannot be rendered in the client.

  • When running in parallel, mesh partitions can only be displayed on the server. If you have a mesh object with Partitions enabled and you display that mesh object on the client, you will not see the mesh partitions due to this limitation.

  • Differences between graphics objects on the server and the connected client will not appear if the displayed options are not available on the client. For example, if you enable Partitions in a mesh object on the server, it will not appear as having changed on the client.

  • Mesh motion preview will not update automatically on the client. Client mesh displays are only updated when you click Display.

  • Symmetry, Mirror Planes, and Periodic Repeats displays are not supported on the client.

  • User-defined colormaps are not available for the client. Any objects on the server using a user-defined colormap will not display on the client.

  • Commands that modify the state of the server (such as initialization), retrieve the latest solver settings when they are sent to the server using the Send Command to Server dialog box. This could result in, for example, the number of specified iterations on the client changing to match the number of iterations specified on the server.

  • Addon modules are not supported with the remote client. If you have an addon module enabled on the server, information regarding the addon module will not be shown on the client. For example, Adjoint residuals will not display on the client.

  • The client cannot display more than 20 windows. If you have more items to plot than 20, consider including multiple report definitions within a single report plot to reduce the number of windows. You can also deactivate report plots to allow for new plots without deleting the existing plots.

  • To reset the graphics window layout in the client you must delete the .flremote.layout file from the operating system home directory, then close and reopen the remote client.

  • Zoom-to-fit does not work on the remote client when the server is iterating. You can pause the calculation to use the zoom-to-fit functionality.

  • If the Reporting Interval in the Run Calculation task page is set to a value greater than 1, residuals plotted on the remote client will respect that reporting interval and will therefore not appear precisely the same as the residuals plotted on the server.

  • Using a virtual private network (VPN) for remote visualization may not work in some situations due to certain firewall security measures in place at the server site. Any disruption in the VPN and/or internet connection may cause an unexpected failure.

  • The viewing and display options available in the remote client are based off of the dimensions of the most recently connected remote session. For example, assume your remote client is connected to two servers, one 3D and one 2D, and the 2D session was connected second. The available display options in the client will reflect the available options for the 2D session, even if you are trying to visualize on the 3D session. To remedy this issue, you can disconnect and reconnect the 3D session, which will make all of the 3D-related display options available in the client.

  • If you want to enable or disable the plotting of residuals, you must do so from within the server session. Sending TUI commands to enable or disable residual plotting using the Send Command to Server dialog box only controls the status of residual plotting in the server, not in the Fluent Remote Visualization Client.
