Program Structure
The program consists of units (modules) of our ATLAS program system, which are linked with each other by input and output variables. Each module represents an independent program provided with an input / output interface.
There is no differentiation between a separate data input process and the calculation process. The ATLAS program system is a simultaneous dialogue - calculation system. Each entered value leads automatically to a processing step as long as the system is determined and the solution is found. The user himself can decide which values are given and which values are calculated.
The basic functions of this module and the editing rules are described in the manual of the ATLAS program system.
The following modules are available in VERD:
