CIVA Simulation Software

No simulations of noise or attenuation were made within this project. The list of modes allows the user to choose which modes to calculate.

Single defect, multiple defects Result display: Beam interaction with flaws or specimens User can simulate a whole inspection process pulse echotandem or TOFD with a wide range of probes conventionalPhased-arrays or EMATcomponents, and flaws. A project was started to evaluate the usability of the software within qualification projects. Numerical simulation is a powerful tool for developing highly accurate and reliable non-destructive ultrasonic inspection methods.

It is also possible to define manually the list of modes to account for in the computations number of skips, internal reflections, mode conversions between layers, etc.

Zone coverage with Ray tracing softsare a single position then a full simulxtion. Continuously variable anisotropy orientation Ogilvy model. This model includes the calculation of attenuation laws and structural noise parameters. Moreover, this tool can display in real time a simple but realistic representation of the ultrasound beam for a given sensor position with divergence angle and near field distance but also to estimate the zone coverage for the whole set of scanning positions and for the different shots if a PA probe is used which makes possible to evaluate at a glance the covered area with the defined settings.

Immersion or contact type, dual element TR arrayphased array Inspected materials: To understand and quantify the impact of influential parameters on a NDT inspection, parametric studies in CIVA are particularly simullation since it is easy and fast to precisely change and monitor parameters.

A mode identification tool allows identifying the different modes that contributes to an echo.

It displays the different wave modes propagated and reflected L waves, T waves and mode conversionsit can display time of flights on the UT path which can help the understanding and analysis of some signals, reflections, displays time of flight, etc. Focused or unfocused, immersion or contact type, dual element TR arrayphased array Defect type: CIVA Ultrasound Simulation Sottware Numerical simulation is a powerful tool for developing highly accurate and reliable non-destructive ultrasonic inspection methods.

Each layer may be isotropic or anisotropic, of arbitrary symmetry and orientation.

Isotropic and anisotropic materials, a specific anisotropic elastic modulus can be set in any direction Inspected shapes: POD calculations Probability Of Detection are available, based on the accounting of uncertain input parameters. CIVA allows the user to compute delay laws and sequences of delay laws for standard and advanced phased-array techniques:.

Materials available are not only metallic ones but can also be fiber composites or granular composites e. In addition, the accredited NDE laboratories are increasingly using software for modeling inspection situations. The calculation can account for multiple skips dimulation the component. The number of skips has no limit. Based on a first set of computations, metamodels can also be calculated in CIVAwhich provides extensive new results to the user in real time, as well as powerful analysis tools such as multi parametric analysis and sensitivity analysis to evaluate the relative impact of influential parameters.

Beam with an immersion transducer with an angle and accounting for multiple skips in the component. Local orientation of the simulatiion and wave fronts can be displayed and saved as animated files, AVI format. SSM has supported university research in the area for many years simulaion, among other things, in the development of a software for ultrasound modeling.

2017:29 Evaluation of the simulation software CIVA for qualification purpose

The Qualification Body has to know softwaee boundaries of such simulation tool to be able to assess the simulation results presented softwwre a technical justification.

Other areas where the Qualification Body can use this simulation tool if verified are parameter studies. This module simulates the beam-defect interaction and predicts the amplitude and the time of flight of various echoes: It is not possible to simulate a complete inspection, or validate an inspection procedure by simulations with CIVA at the current time.

Homogeneous or heteregeneous components, different material properties. An advanced ray tracer is connected to CIVA simulation modules. Both the producer simulatino simulated data and the evaluator must have great knowledge about the CIVA software to be able to draw the right conclusions from the results.
