The Feko Source Data Viewer is a tool that allows you to view the
currents per frequency for a PCB current data, defined using a .rei file.
In the model tree, under Field/Current Data, select a PCB current data. From
the right-click context menu, click Visualise PCB Current Data.
The tool allows you to view multiple PCB current data definitions by using the
Import Currents Source data tool to import additional current
source data. For each currents source data (.rei file), you can specify the frequency, layers and nets that you want to
view, as well as scale the layer height in the 3D view. Figure 1. The Feko Source Data Viewer tool where you can view currents
per frequency for a PCB current data definition.
Field/Current Data, select a PCB current data. From
the right-click context menu, click 
Visualise PCB Current Data.
