Courses which are to be scheduled in the timetable grid at the same time are in a so-called cluster. These clusters are also sometimes called blocks, and the term bands is also often used.
Cluster = band
In the 'Students timetables module, courses taking place simultaneously are combined in Untis into clusters . The clusters in course scheduling are nothing more than clusters.
The course scheduling module provides a comfortable tool for working with clusters, the course-cluster-matrix .
You can see the available courses in the rows of the matrix and the existing clusters in the columns. The cells then indicate which course belongs to which cluster.
The course-cluster-matrixis described later in the section of the same name.
