3. Initial model setup
There are several ways in which you can define the initial geometry of your model setup:
The build-in geometries and Matlab/Octave files allow you to specify the initial temperature structure. In addition, you can also independently set a temperarature profile with:
In some cases you might be interested to start with a different temperature profile, such as a steady-state temperature profile for your setup. See:
By default, the internal free surface is set to a constant value. In some cases that is insufficient and you can also set the initial topography with a file:
