The ATHLET Program Package comprises a series of auxiliary programs to support both the ATHLET users and the code developers in the application and development of ATHLET.
All programs run under Windows, some of them under Unix and Linux, too.
ATHLET Input Graphics Program
The ATHLET Input Graphics Program (AIG) creates a graphical representation of an ATHLET input data set. It gives support to the examination and documentation of the geometry and nodalization of an input data set. Furthermore, the ATHLET input graphs can be used as a basis for the dynamic visualization of ATHLET results applying the Analysis Simulator ATLAS or the post-processing tool ATLAS-DyVis.
GCSM Input Graphics Program GIG
The GCSM Input Graphics Program generates a graphic representation of the logical structure of a GCSM control signal defined within the ATHLET input data. It is a very useful tool for checking the correctness of the GCSM input data, as well as for documentation purposes.
The GCSM signal graph of an ATHLET simulation model can be used as a basis of the dynamic representation of ATHLET results applying the Analysis Simulator ATLAS or the post-processing tool ATLAS-DyVis.
GCSM Input Data Generator
GCSM structures (General Control Simulation Module) enable the simulation of control and balance-of-plant as well as of simple thermo-fluid dynamic systems. The representation of a reactor control requires many thousands of single GCSM controllers. The GCSM generator is a valuable tool which
- enables the creation and interconnection of graphic symbols of the
different GCSM controllers (knowledge base)
- checks the consistency of the knowledge base
- simulates the functionality of the knowledge base
- creates GCSM input data for ATHLET
The GCSM generator was developed by GRS on the basis of the expert system shell G2 of Gensym, USA (license required!).
JSPLOT is the most powerful and flexible plotting program running on all common computer platforms. The main features are:
- Generates time and locus diagrams
- Exploits the ATHLET plot header data
- Content and layout of the plots is stored in a Plot Description File
which is saved to be reapplied.
- Applicable also under ATLAS-DyVis
- Interactive modification of the plot design
- Export formats: cgm, emf, eps, png, wmf
In addition, plots can be created using the plotting programs QUICKPLOT or MS Excel.
The ATLAS-DyVis (Dynamic Visualization) software is the graphic module of the ATLAS Analysis Simulator. It can be applied for the graphical representation of results created by a simulation program like ATHLET (thermo-fluid, heat conduction, control data). Its primary purpose is to display the course of a simulation by dynamic data visualization in animated pictures ('movies'). Selected physical quantities may be depicted as graded colors filling a spatial nodalization scheme, which gives a well grounded survey of the simulation.
In addition, ordinary time plots (trend curves) of all available variables can be generated and saved as trend sets to be reapplied within ATLAS-DyVis or by the ATHLET plotting program JSPLOT.
The operation of ATLAS-DyVis is fully interactive.
