Non-destructive testing: better practices through simulation
As a simulation software platform for non-destructive testing (NDT), CIVA makes it possible to design and optimise inspection methods. The goal? To enhance product quality as well as human and facility safety by detecting flaws with precision.
Non-destructive testing (NDT)
includes all processes involved
in inspecting a part and identifying
any flaws that might adversely
affect its function. Capitalising on research
outcomes obtained by CEA and
its partners(*) in this area, the simulation
software platform Civa was developed
in 1993 and has since integrated various
enhancements and advances. Comprising
a set of modules to simulate and process
data, version 9 uses several techniques:
ultrasound, eddy currents, radiography.
Civa is used in a number of industrial processes.
Simulation makes it possible to
conduct virtual tests from the engineering
department, design new test methods, demonstrate performance, plot PoD
curves, compile qualification files, understand
complex phenomena in heterogeneous
or anisotropic parts, and design
new translators or probes.
Boasting an industry-oriented interface,
the Civa platform offers innovative tools.
Specific functionalities make it possible to
configure multielement sensors in complex
arrangements and assess the performance
of new probes, based on the
most recent technologies.
Available throughout the world, Civa is
used by industry groups in more than
29 countries. Civa has become the NDT
simulation benchmark and is progressively
evolving into a software integration platform. New modules developed by universities
as well as French and European
companies (Moderato by EDF, Sindbad by
CEA Léti) have been added to the latest
versions to tailor to industry needs.
