PAUT and TOFD Simulations with CIVA

HRL utilises ultrasonic simulation software called CIVA, which was developed by the French Commission for Atomic and Alternate Energy (CEA). CIVA is capable of accurately simulating complex Phased Array, Time of Flight and Conventional Ultrasonic models in 2D and 3D geometries.

HRL utilises CIVA to;

  • demonstrate and prove out inspection concepts with the ability to optimise configurations
  • validate many "what if" scenarios, thus minimising the need for so many validation blocks with artificial defects inserted
  • verification of signal responses to differentiate between those from geometries and those from defects
  • probe design and optimisation prior to manufacture
  • training and realisation of ultrasonic phenomena

Customised Ultrasonic Inspection Rigs

Often HRL is called upon to provide ultrasonic inspection services where others have declined.

HRL offers professional customised ultrasonic rig development for those impossible to reach situations. This is done in-house using 3D CAD and additive manufacturing (3D Printing) technologies. Our in-house Concept/Design/Manufacture/Implement service allows for a comparably rapid execution of your inspection requirements. Implementation is carried out by our expert engineers and/or by our clients themselves.

HRL can build fully automated robotic inspection systems in-house using CNC control logic technology. These types of systems can be designed for specific geometry applications for high volume economical inspection requirements.

Coupling these abilities with CIVA ultrasonic simulation software, the requirements for physical expensive validation blocks can be reduced.

Innovation in our methodologies and concepts have benefited many of our valued clients, while displacing some of the expensive OEM's imported service providers.
