Introduction

Ensight is 3D Computational Fluid Dynamics (CFD) result viewing software developed by CEI Inc. The software can be downloaded from the CEI website.

This page contains a brief introduction to the software for the purpose of viewing and analyzing TUFLOW results. More advanced user tutorials are available via the CEI website. Ensight Tutorials.

Basics

Navigation Tips and Shortcut Keys

Left Mouse Button
Holding the left mouse button whilst navigating in the viewport (graphics display)

Navigating mouse up-down = rotate about horizontal screen X-axis
Navigating mouse left-right = rotate about vertical screen Y-axis
Ctrl-key plus up-down or left-right navigation = rotate about Z-axis extending outward from the screen

Right Mouse Button
Holding the right mouse button whilst navigating in the viewport (graphics display)

Navigating mouse up-down or left-right = Model zooms in and out
Ctrl-key plus right button acts as a pan operation

Middle Mouse Button (Scroll)

Model zooms in and out

Shortcut Keys
F1 - Window will rotate about the screen X-axis by 45 degrees
F2 - Window will rotate about the screen Y-axis by 45 degrees
F3 - Window will rotate about the screen Z-axis by 45 degrees
Ctrl F1, F2, F3 rotates by -45 degrees about the screen axes

F4 - Spins the window – (try with the left mouse click)
F5 - Front view
F6 - Side view
F7 - Top view
F8 - Will return to last view before F5, F6 or F7 was pressed
F9 - Maximizes the graphics windows on the display; press F9 again or use Esc to go back

Loading a Background Image

Background Images can be registered and added to a display.

The utility "Align Photo" is required to do this. This option is not available within the basic Ensight package. CEI Inc. should be contacted so that this utility can be added to your user define tools list.

Steps to load aerial imagery are:

Select the Part which you would like to to apply the photo to.
Double Click the “Align Photo” button from the user define tools list.

A dialog will appear, asking you to select the Image File, and the corresponding World Coordinates File. Select the “Relative Position” option (EnSight models are currently stored in relative coordinates).
Enter the Image File and World File.

Select "OK".
Select "Xref" and Yref" for the offsets.

Result Long-section Plot

Create a clip line in the location where you would like to extract results.

Select the clip line icon

Relocate the clip line. Selecting the centre is used to shift the location of the clip line. Selecting the start or end of the line can be used to alter the line extent.

Select the parent Part 2D TUFLOW Elements
Right Click >> Create >> Clips
Name the Clip
Select Tool = Line
Select Extents = Finite

Deselect the clip line tool.

The clip should now remain within the view window and also show in the list of Parts

Variables need to be associated with the clip:

Select the clip part (left click the Part)
Select query
Select Sample = 1D part over distance
Select the desired variable. For example Depth or Water_Level

This dataset will be added to the Plots/Queries window, and also to the display window as a graph. Double click the graph in the display window to update the graph display options (colors, labels, titles etc.).
