INTRODUCTION
Before being officially released, each version of GRAITEC software, including
Advance Design, undergoes a series of validation tests. This validation is performed in
parallel and in addition to manual testing and beta testing, in order to obtain the
"operational version" status. This document contains a description of the automatictests, highlighting the theoretical background and the results we have obtained using
the current software release.
Usually, a test is made of a reference (independent from the specific software version
tested), a transformation (a calculation or a data processing scenario), a result (given
by the specific software version tested) and a difference usually measured in
percentage as a drift from a set of reference values. Depending on the cases, the
used reference is either a theoretical calculation done manually, a sample taken from
the technical literature, or the result of a previous version considered as good by
experience.
Starting with version 2012, Graitec Advance has made significant steps forward in term ofquality management by extending the scope and automating the testing process.
While in previous versions, the tests were always about the calculation results which
were compared to a reference set, starting with version 2012, tests have been
extended to user interface behavior, import/export procedures, etc.
The next major improvement is the capacity to pass the tests automatically. These
current tests have obviously been passed on the operational version, but they are
actually passed on a daily basis during the development process, which helps improve
the daily quality by solving potential issues, immediately after they have been
introduced in the code.
In the field of structural analysis and design, software users must keep in mind that theresults highly depend on the modeling (especially when dealing with finite elements)
and on the settings of the numerous assumptions and options available in the
software. A software package cannot replace engineers experience and analysis.
Despite all our efforts in term of quality management, we cannot guaranty the correct
behavior and the validity of the results issued by Advance Design in any situation.
With this validation guide, we are providing a set of concrete test cases showing the
behavior of Advance Design in various areas and various conditions. The tests cover
a wide field of expertise: modeling, climatic load generation according to Eurocode 1,
combinations management, meshing, finite element calculation, reinforced concrete
design according to Eurocode 2, steel member design according to Eurocode 3, steel
connection design according to Eurocode 3, timber member design according toEurocode 5, seismic analysis according to Eurocode 8, report generation, import /
export procedures and user interface behavior.
We hope that this guide will highly contribute to the knowledge and the confidence you
are placing in Advance Design.
