What’s New in CDEGS

Specialized Packages

SESResap: A New Soil Resistivity Measurement Editor

This is the first (Beta) release of the SESResap module. This module acts as a complete replacement for CDEGS – Specify for RESAP. It can load and save all existing RESAP files. Cases can also be run from within the program and both the input data and the computation results can be visualized from this same environment.

The new program also includes enhancements compared to CDEGS – Specify:

· Clearer schematics with electrode labelling that follows popular conventions from instrument manufacturers,

· Measurements data grid with optional columns that help verify the input data,

· Possibility of adding comments for any data point,

· Interactive plot of the data,

· Clearer specification of analysis parameters,

· Useful field data sheet that helps achieve quality measurements.

A New Interface for CDEGS

First and foremost, the CDEGS main interface that acts as a front-end for packages in the MultiGround, MultiGroundZ, MultiFields, and CDEGS families has been updated to adopt the new look and feel that is now standard for SES programs. This new version of CDEGS supports all the features of the original version of CDEGS, and can be used interchangeably with that program. It also adds some interesting enhancements, in particular with respect to the selection of the Session Mode and with the management of the JobID list.

A New Interface for FFTSES

This is also the first Beta release of the SESFFT module, the new user-interface module for the FFTSES engineering program. As is the case for SESResap, this new program offers full support of existing FFTSES files and can be used instead of CDEGS – Specify for FFTSES. As for all new SES Software user-interface programs, SESFFT offers a fully integrated work environment for FFTSES. It allows you to edit and visualize input data, run the computations (in both Forward and Inverse mode) and visualize the computation results. It also includes tools to help build the FFTSES Input Databases starting from HIFREQ or MALZ computation databases.

The new program also includes several new features and improvements compared to CDEGS –Specify, including the direct visualization of the frequency spectrum of the input signal in Forward mode, the specification of window or regularization functions to smooth out time-domain signals and attenuate undesired high-frequency components, and others.

New SES Software Tool for Soil Model Design

Another addition to SES Software is the new Soil Model Editor module. This module, which can be used as a stand-alone program but is also used as a component in several other SES Software programs, allows editing the various soil structures that can be used in SES Software. It can currently be used to edit soil structure data for the MALT, MALZ, HIFREQ, and TRALIN programs but will eventually be capable of performing this task for all SES Software programs requiring soil structure data, making it easier to share soil structure data between those programs. It is currently integrated into the SESTRALIN and SESCAD programs.

Introducing the New SES Object Library

SES Object Library is another new program included in this version of the software. This program allows you to inspect the properties of a large number of components that can be part of models for many SES Software engineering programs. It currently includes a comprehensive database of conductors as well as several power cables; many other components will be added to the library in the near future.

The user-interface of the program makes it easy to search the library for desired items. The available items can be filtered in many different ways and sorted according to any of their properties. A large number of properties are available to help identify the most suitable items for the task at hand.

This module is currently available as a stand-alone program but will eventually be integrated as a component in several other SES programs, where it will act as a replacement for the existing SES Conductor Database and other libraries currently available in the software.

SESPlotViewer and the SES Plotting Engine

SESPlotViewer is a new SES Software program that can display data as plots of various types. The program also displays that same data in tabular format, and optionally allows editing it.

The main use of this program is as a plotter for the computation results produced by some SES Software engineering programs, notably SESEnviroPlus, but it can also be used to create plots from scratch, using your own data.

The plots displayed by the program are interactive. You can zoom anywhere in the plot using the mouse wheel; pointing the mouse at any point on a plot brings up a window showing the values of the nearest data point.

Fonts and colors can be customized for many plot elements, including the axis labels and the plot title. The plot can be copied to the Windows clipboard to be included in reports or saved to disk.

This program is based on a new SES Plotting Engine component which will eventually be integrated in all SES Software user-interface programs that need to plot data; it already plays this role for the new SESFFT program described previously.
