With this in mind, the year 2000 has been one of consolidation at SES. The foundations of the software have been restructured, to make it easier to integrate new technologies as they become available. This should allow us to adapt more quickly to future changes in computing environments and to deliver promptly the features that you want to see in the software.

This strategy is already starting to bear fruits. Some long-awaited features have been implemented in the plotting package, such as complete customizability of the graphical characteristics (line-width, colors, fonts…), new ‘Configuration’ plotting capabilities (plot the GPR directly on the grid, etc.), ‘Configuration’ data filters that allow you to focus your attention on selected parts of the grid (based on the properties of the grid’s conductors), multiple zoom zones and exclusion zones, etc. Look forward also to several new features in SESCAD, such as a drawing grid, data filters similar to those of the output module, new path–related tools that allow you to perform several operations on connected conductor segments, a new tower creation wizard, etc.

This isn’t to say that the research work and the development of the engineering software were left out during the past year, quite the contrary. The problems that plagued the two-layer soil model in HIFREQ since its inception have finally been solved. By the same occasion, the current calculation phase of the program was accelerated substantially. Also, research into a multi-layer HIFREQ is well under way. Other developments of note include a model for a current source in SPLITS and the ability to compute the self impedance of conductors of arbitrary shape in TRALIN.
