CIVA

CIVA is a simulation and analysis platform for non-destructive testing (NDT). The French research centre CEA LIST develops it, and EXTENDE, a CEA spin-off, has been its only worldwide distributor since 2010. Engineers use it to model an inspection before running it on real hardware. They define the specimen, material, probe and flaw, then predict the signals an inspection would produce. Modules cover ultrasonic testing (including phased arrays and Total Focusing Method), eddy current testing (including steam generator tube inspection), radiography with computed tomography, guided waves, structural health monitoring and thermography. Specimens can be built from canonical shapes, predefined components such as nozzles and welds, or imported 2D and 3D CAD. The software also includes statistical tools: probability of detection (POD) curves, metamodels and sensitivity analysis. CIVA 2025 added a finite element perspective to the UT module, alongside the existing semi-analytical models, so users can cross-check results between the two. CIVA Script exposes a Python API, and the CIVA Data Science module trains machine-learning classifiers on a mix of simulated and real data. The UT analysis tools can import real acquisition data from several instrument makers. Customers are mostly large companies in nuclear, aerospace, energy, petrochemical and manufacturing, plus probe manufacturers and qualification bodies. CIVA Education is a simplified edition for universities and training centres. Modules can be bought or rented, alone or in bundles, as single-computer or network licences. Updates come with a maintenance contract. No prices are published, and there is no self-service download or public trial. The main limitation is that CIVA is a specialist tool for NDT experts: it does not manage assets, work orders or inspection records.
