phases. In this example water is located at the entrance part of the domain between the inlet
and pipe spillway. In the Initial Conditions tab, the initial conditions for the simulation are
set. In this tutorial advanced initial conditions are used.

Figure 4.29: Spillway: Initial Conditions

The initial velocity can be defined in a C++ file initialconditions.cxx. A template of an
initial condition file can be found in the reference folder (spillway in Tutorials folder).

• Copy the file initialconditions.cxx from the subfolder Tutorials/4.5 - spillway of the
Public/Documents/TransAT5.7 folder to your project folder.

• Select Advanced Initial Conditions
• Click to compile the initial conditions. This step is optional and only checks that
the initialcondition.cxx file is written properly and can be compiled. The flow field will be
initialised later in the Execute window.
