CIVA simulation and analysis software for non-destructive testing (NDT)

CIVA is the world’s leading simulation and analysis software for non-destructive testing (NDT). It is widely used in industry, research, and education to design, optimize, qualify, and study non-destructive testing methods. CIVA can also help improve diagnoses and support the implementation of automated inspection procedures. It can handle all the main inspection techniques. CIVA is developed by CEA-List and distributed by Extende in more than 40 countries.


Simulating inspections, analyzing data

CIVA simulation and analysis software was developed specifically for non-destructive testing (NDT).

The CIVA suite is modular and offers a wide range of features. Custom tools developed with CEA-List and partners can also be integrated into CIVA. The software was developed by CEA-List and is distributed by Extende.

CIVA can help assess the feasibility of an inspection procedure or choose the most appropriate one for a given use case. It can also be used to design new processes, optimize configurations, and demonstrate the performance of an inspection technique. It integrates ultrasonic, guided wave, SHM, eddy current, thermography, radiography, and tomography—all of the main inspection techniques used in the manufacturing and other industries and in maintenance.

CIVA is more than a simulator. It can also analyze real and simulated measurement data and includes a suite of statistical analysis and performance demonstration tools with features like metamodels, sensitivity analyses, and probability of detection (PoD) analyses. CIVA can also fully or partially automate diagnoses.

Used by more than 300 companies in the energy, aeronautics, transportation, petrochemical, and manufacturing industries, CIVA is the world’s leading NDT software suite.


Powerful, multi-technique tools for a variety of business cases

CIVA offers several major advantages:

  • Multi-technique: CIVA can be used for ultrasonic, guided wave, eddy current, thermography, radiography, and tomography—all of the main inspection techniques. It also has a structural health monitoring (SHM) module.
  • Multi-physics: CIVA’s vast array of integrated models can be used to study the various physical phenomena inherent to different inspection techniques. Rapid semi-analytical numerical solutions (finite element, integral equations, and Monte Carlo methods) can be combined in CIVA. The software can also recommend the optimal simulation strategies depending on specific configurations and objectives.
  • Data processing and analysis: CIVA has advanced imaging and data processing features like reconstruction and X-ray tomography, modal analysis, segmentation, and diagnosis.
  • User environment: CIVA’s intuitive graphical user interface is designed to facilitate a use-case-centered approach that aligns closely with NDT standards. It offers interactive or script-based call handling and automates calculation campaigns (parametric variations, propagation of uncertainties).
  • Customization: Proprietary plug-ins can be added to CIVA for custom simulation and analysis. Custom CIVA development work can be completed rapidly through a partnership with the CEA (contact:

Nuclear, aeronautics, petrochemicals, transportation, and more

  • Nuclear: control system design and optimization; process qualification assistance; robotic controls; welding and complex materials; data analysis for thick, forged, cast components and bimetal connectors; etc.
  • Aeronautics: inspection of complex parts, composite materials (with a specific CIVA module), detection probability calculation, SHM, etc.
  • Petrochemicals: pipe inspection, ultrasonic, guided waves, pulsed eddy current, analysis of complex phenomena, method validation assistance (with a specific CIVA module).
  • Transportation: rail inspection, guided wave, SHM, etc.
  • Manufacturing: part inspection and process control assistance, post-manufacturing quality control, characterization, monitoring, and additive manufacturing.
Use case 1

Probe and trajectory optimization

CIVA simulation tools help rapidly find the optimal solution for a given performance target.

The software’s wide range of probe and sensor models makes it easy to design new probes optimized according to a variety of parameters. Parametric and complex inspection trajectories can be programmed and their coverage (in terms of control sensitivity) verified and maximized.

Use case 2

Simulation of inspection methods for performance demonstration

CIVA includes performance demonstration tools to:

  • Create metamodels to enable the intensive simulations (several thousand evaluations per second) necessary for statistical studies.
  • Assess the sensitivity of an inspection to critical variables and uncertainties (Sobol index).
  • Assess probability of detection (PoD) based on customizable criteria (experimental uncertainty ranges and rules, noise and detection thresholds, detectability criteria, etc.).
  • Identify the limits of validity of an inspection according to a given definitional domain.
Use case 3

Automated diagnosis

Diagnosis is a key step in the inspection process. Automating this step is crucial to an inspection process’ reliability and productivity.

CEA-List has added assisted and automated diagnosis tools to CIVA. The software now offers machine learning modules (CIVA 2022) that can use real and/or simulated data logs to learn to produce a diagnosis.
