EikoTwin Digital Twin
EikoTwin Digital Twin allows the engineer to improve their simulation by making the most of their test data.
It implements "augmented simulations", which use the measured data as boundary conditions, but also allows the identification of material parameters to bring the simulation closer to the expected result.
Principle
- Integration of test results for the validation of simulations.
- Import of sensor measurements and direct comparison with the simulation result.
Features
- Use of measurements to enrich the simulation model.
- Creation of measured boundary conditions to release idealized conditions.
- Export of a simulation model enhanced with measurement information.
Results
- Quantification of errors due to boundary conditions.
- Automatic identification of the simulation parameters required (materials, etc.).
- Determination of the residual model error.

Applications and tutorials
Camera calibration: principles and procedures
The use of a multi-camera system for metrology and accurate measurements requires the calibration of these cameras. They can be represented mathematically by a projection model, in the form of a matrix, allowing the passage of the position of 3D points to their projection in 2D image space. The process of estimating the parameters of…
EikoTwin DIC and the measurement of small strains
Innovation in the automotive industry Innovation is at the heart of the automotive industry: autonomous vehicles, shared mobility, advanced equipment, etc. In order to reinvent themselves and remain competitive, it is necessary for automotive industries to innovate and develop new technologies. It is therefore essential for these companies to perform realistic simulations. The objective is…
The Batch mode: a new EikoTwin DIC plugin
In order to continuously improve the features offered by EikoTwin DIC software, EikoSim has developed a new optional plugin: the Batch mode. It enables to launch, through a configuration file prepared beforehand, the pre-calibration, calibration and displacement measurement for several EikoTwin DIC projects in EKT format. This partial automation of the data processing ensures significant…

Safran Ceramics trusts EikoSim with the “Thermal” plug-in
Benjamin Lacombe is a Mechanical Design Engineer at Safran Ceramics. He tells us about his experience with EikoTwin DIC and the development of the “Thermal” plug-in. « I work at Safran Ceramics, Safran group’s center of excellence for high-temperature composites. We are in charge of developing high-temperature solutions for tomorrow’s aircraft. We conduct a large number…
Technical functionality: selection of the measurement mesh
On EikoTwin DIC, the measurements are directly expressed on the simulation mesh. In order to choose which areas of interest for the test are visible to the camera(s), the so-called measurement mesh must first be selected. Indeed, this mesh will be the one where the results will be calculated. It is therefore essential to select…
