The network shown below is used to create the visualisations shown in Section 2.2.
This section of the network reads the data and prepares it for visualisation.
After scaling with the ScalePositions2D macro, a Compute module
is used to implement Equations 5 and 6 to convert
the cylindrical polar vector data into Cartesian vector data. These equations
require the value of 
, which is provided to the Compute
module via a Remove and Replace module. This gives a field
where the data value at every point is just the position of that point. Since
the data contains values at 
and 
, the arrow
at these positions overlap and can differ due to numerical instabilities in
the dataset. To avoid confusion, the Slab module is used to remove
one of them.
