EikoTwin Digital Twin
The EikoTwin Digital Twin is a highly effective tool to enhance simulation model calibration accuracy.
This innovative technology relies on digital models that are specifically calibrated using test data, ensuring that the resultant simulations provide highly accurate and reliable results.
Digital twin technology implements "augmented simulations", which use the measured data as boundary conditions, but also allow simulation-enabled model calibration of material model parameters to bring the simulation closer to the expected result.

VVUQ references & resources for solid mechanics & aerospace
By Florent Mathieu, CEO of EikoSim After several occasions where I’ve been given advice to consult specific documents in the field of validation testing and VVUQ (Verification, Validation, and Uncertainty Quantification), I’ve decided to write a blog about this. Here is a more detailed list of important papers, books or websites that I found along…
What is VVUQ (Verification, Validation, and Uncertainty Quantification)?
By Florent Mathieu, CEO of EikoSim In the world of scientific simulations, ensuring accuracy, reliability, and credibility is of utmost importance. To achieve this, scientists and engineers employ a rigorous process called Verification, Validation, and Uncertainty Quantification (VVUQ). This blog article explores what VVUQ entails, its applications across various software product domains, and its role…
Digital Image Correlation – The basics
By Florent Mathieu, CEO of EikoSim What is digital image correlation? The Digital Image Correlation (DIC) technique is a non-contact, full-field measurement approach that enables the assessment of the deformation and motion of objects. This is achieved by comparing digital images of the object before and after deformation. DIC measurement is a technique used to…
How to make a speckle pattern suitable for Digital Image Correlation?
Context: Speckle patterns & digital image correlation The principle of image correlation is based on tracking information from a so-called “reference” image in the following images, often called “deformed images.” When using digital image correlation (DIC), speckle patterns are created on the surface of a specimen to address uniqueness concerns. As a result, the accuracy…
Integrating multi-camera DIC at MBDA
As part of its increasing competence in cutting-edge measurement techniques, MBDA has launched a process of testing and internal auditing of measurement resources by multi-camera DIC (Digital Image Correlation). After testing these measurement tools on coupon-type test campaigns, a new stage has been launched with the testing of this technology on more complex structures using multi-camera systems. Compressive…
