This “quick start” tutorial will demonstrate some of the basic features of
Phase2 using the simple model shown above. You will see how quickly
and easily a model can be created and analyzed with Phase2.
The finished product ofthis tutorial can be found in the Tutorial 01
Quick Start.fez data file. All tutorial files installed with Phase2 8.0 can
be accessed by selecting File > Recent Folders > Tutorials Folder from the
Phase2 main menu.

Model
If you have not already done so, run the Phase2 Model program by
double-clicking on the Phase2 icon in your installation folder. Or from the
Start menu, select Programs →Rocscience → Phase2 8.0 → Phase2.
If the Phase2 application window is not already maximized, maximize it
now, so that the full screen is available for viewing the model.

Note that when the Phase2 Model program is started, a new blank
document is already opened, allowing you to begin creating a model
immediately.

ProjectSettings
The Project Settings dialog is used to configure the main analysis
parameters for your Phase2 model.
Although we do not need to customize the Project Settings for this
tutorial, let’s take a look at the dialog.

Select: Analysis → Project Settings

Since we will be using Metric (MPa) units for this tutorial, you should
make sure that the Units option is set to Metric, stress asMPa, under the
General tab. This determines the units of length, force, stress and unit
weight used in the analysis.
NOTE: Phase2 remembers the most recently selected Units in Project
Settings, and uses this as the setting for all new documents.
Select the Stages tab, and note that we will be analyzing a single stage
model. (Multi-stage modeling is covered in the next tutorial).
Select theProject Summary tab and enter Quick Start Tutorial as the
Project Title.
Do not change any other settings in the dialog. Select OK.

Entering Boundaries
First create the excavation as follows:

Select: Boundaries → Add Excavation
Enter the following coordinates in the prompt line at the bottom right of
the screen. Note:press Enter at the end of each line, to enter each
coordinate pair, or single letter text command (e.g. “a” for arc).
Enter vertex [t=table,i=circle,esc=cancel]: -5 10
Enter vertex [t=table,a=arc,i=circle,u=undo,esc=cancel]: -5 0
Enter vertex [...]: 5 0
Enter vertex [...]: 5 10
Enter vertex [...]: a
You will see the Arc Options dialog.
Select the 3 Points on Arc option, Number of Segments =20.
Select OK.
Enter second arc point [u=undo,esc=cancel]: 0 15
Enter third arc point [u=undo,esc=cancel]: c

By entering “c” at the last prompt, the arc closes on the first point of the
excavation. Note that arcs in Phase2 are actually made up of a series of
straight line segments. The Arc option and many other useful shortcuts
are also available in the right-click menu.
Select Zoom All(or press the F2 function key) to zoom the excavation to
the center of the view.
Now we will create the external boundary. In Phase2, the external
boundary may be automatically generated, or user-defined. We will use
one of the ‘automatic’ options.

Select: Boundaries → Add External
You will see the Create External Boundary dialog. We will use the default
settings of Boundary Type = Box andExpansion Factor = 3, so just select
OK, and the external boundary will be automatically created.

The boundaries for this example have now been entered.

Meshing
The next step is to generate the finite element mesh. In Phase2, meshing
is a simple two-step process. First you must Discretize the boundaries,
