ISIS 2D Quick Tour - Halcrow

ISIS 2D
Quick Tour
ISIS 2D has a fully hydrodynamic computational engine
designed to work alone or with ISIS 1D, enabling dynamic
interaction between 1D and 2D models.
Download ISIS FREE from the user website (www.isisuser.com)
and follow the five steps below in order to get your first model
up and running in less than five minutes!

Note: ISIS 2D
creates a folder
‘DefenceBreach_01’ in
the same folder as the
ISIS 2D control XML file
mentioned earlier to
store the results.
STEP 3:
CLICK RUN
Once the XML file is successfully
loaded, click ‘Run’ in the lower left
corner to start the simulation. A new
window appears showing the progress
of the simulation. On completion, the
following message will appear: “Run
Successful – Stopping. Press Return
to Close”. Press Enter to obtain
the results.
STEP 2:
LOAD XML FILE
ISIS 2D uses an XML file to locate
component files. For this exercise, we will
use the example of flow in floodplain
environments (file: Defence-Breach.xml).
Select ‘File’ and ‘Open’ and browse to the folder
where ISIS is installed (by default it is C:/isis). Browse
to \data\examples\ISIS 2D\Site1, select Defence-
Breach.xml and ‘Open’. The XML file is now loaded
within the interface. The data required for this
simulation is also available under the different
sub-tabs in the Domain tab.
STEP 4:
LAUNCH ISIS MAPPER
AND LOAD RESULTS
Launch the visualisation tool by selecting
‘Run’ and ‘ISIS MAPPER’. Once open, select
‘Layer’ (found at the top of the interface), ‘Add
Layer’ and load the aerial photography (C:\isis\-
data\examples\ISIS 2D\Site1\GIS\Airphoto.jpg)
and modelling results (C:\isis\data\examples\ISIS
2D\Site 1\DefenceBreach_01\01.2dm). Upon
selecting 01.2.dm another window will open
with a list of 2D model results variables.
Here select the result file with water
level (01_waterlevel.dat).

STEP 1:
OPEN ISIS 2D
STEP 5:
ANIMATE RESULTS
In the List of Layers (found in the left
hand column) right-click on the
file 01_waterlevel.dat. Select ‘Animate’
and then in the animation toolbar
click ‘Run Animation’. The animation of
the water levels at different time steps
will be represented in blue over the
ground surface photography.
Note: The GIS
files linked to the
model can be found
under the ‘GIS’ folder
at the same location.
We will view some
of these in
Step 4.
Once ISIS is installed, go to the ‘Start’
menu and select ‘Programs’. Then select
the ISIS group and click on the
ISIS 2D item.
Alternatively you can open ISIS using
the desktop icon and access the
ISIS 2D interface from the
Run menu.
That’s it! You’ve produced
and viewed the results of
your first ISIS 2D simulation
