| − | Ensight is a 3D computational fluid dynamics viewing software. An elevation dataset is required to lock the 2D TUFLOW results to a fixed horizontal plan (2D space). The TUFLOW model output result data type ''ZH'' is required for this purpose. This must first be specified as a TUFLOW command prior to running the simulation. Steps required to flatten the dataset are outlined in the flowing section, "Loading Data" <br>(eg. ''Map Output Data Types == h v q d <b>ZH </b>)''
| |
| − | | |
| − | == Loading Data ==
| |
| − | Run the TUFLOW utility RES_to_RES.exe to create the Ensight input data files from TUFLOW xmdf output.<br>
| |
| − | Open the case file (*.case) in Ensight.
| |
| − | | |
| − | [[File:Ensight_001.JPG|800px]] <br><br>
| |
| − | | |
| − | This will load the 'Part' titled: ''2D TUFLOW Elements'' as Case Item 1.
| |
| − | | |
| − | [[File:Ensight_002.JPG|800px]]<br><br> | |
| − | | |
| − | Select the "Variables" tab within the data management window (bottom left) to view the model result scalar and vector datasets that were loaded.<br>
| |
| − | Activate the relevant dataset that you would like to work with. In this example we have selected, Depth, Unit Flow, Velocity and Water Level.
| |
| − | | |
| − | [[File:Ensight_003.JPG|400px]]<br><br>
| |
| − | | |
| − | These results can be viewed by creating an isosurface of the dataset within the ''2D TUFLOW Elements'' Case Item.
| |
| − | | |
| − | Right Click ''2D TUFLOW Elements''
| |
| − | Select >> Create >> Isosurfaces
| |
| − | | |
| − | [[File:Ensight_004a.JPG|800px]]<br><br>
| |
| − | | |
| − | Within the isosurfaces window:
| |
| − | # Select 'Advance' (top right)
| |
| − | # Enter a unique name for the dataset. This will become the child Part name. (''2D TUFLOW Elements'' is the parent Part title)
| |
| − | # Select the ''Variable'' you would like to visualize (e.g. Depth)
| |
| − | # Set ''Creation Type'' = Isovolume
| |
| − | # Set ''Constraint'' = Banded
| |
| − | # Define the isovolume range. The upper and lower extreme values for the datasets are listed within the variables table (bottom left of the interface)

| |
| − | [[File:Ensight_005a.JPG|800px]]<br><br>
| |
| − | | |
| − | Update the variable display contouring:
| |
| − | # Select the newly created Part (right click)
| |
| − | # Select ''Color by >> Select Variable''
| |
| − | # When contouring, select the relevant maximum dataset. For example, for time varying ''Depth'' data, select ''Max_Depth''. This will lock the contouring to the range of the maximum dataset. Block colors and transparencies can also be defined using this selection.

| − | The colour palette can be modified by selecting the defining dataset within the variable list: <br>
| |
| − | Right Click >> Edit Palette <br>
| |
| − | [[File:Ensight_017.JPG|600px]]<br><br>
| |
| − | | |
| − | The final visualization step requires that the parent Part, ''2D TUFLOW Elements'' be flattened. Ensight is a 3D computational fluid dynamics viewing software. Flattening the parent Part locks the TUFLOW dataset to a fixed horizontal plan (2D space).
| |
| − | # Select the parent Part, ''2D TUFLOW Elements'' (right click)
| |
| − | # Select Edit
| |
| − | # Set the Coordinates scale factor = <b>-1</b> *variable
| |
| − | # Set the Z variable = <b>''Fixed_Bathymetry''</b>. For this option to be available, the model result data type ''ZH'' must be defined as a TUFLOW output (eg. ''Map Output Data Types == h v q d <b>ZH </b>
