Reality-inspired simulations

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.

Testimonials

IRT Saint Exupery

Using EikoTwin allowed us, through augmented simulation, to correct overly idealized boundary conditions, or to isolate regions of interest. The inverse identification proposed by Digital Twin also gave very promising results for reviewing the calibration and validation processes of the models by reducing the number of tests.

Camera calibration: principles and procedures

PinholeModelCamera

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…

Technical functionality: selection of the measurement mesh

Capture

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…
