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.

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 outputs.
  • Creation of measured boundary conditions to release idealized conditions for model calibration.
  • Export of a digital twin prototype simulation model enhanced with measurement information.

Results

  • Quantification of virtual model errors due to boundary conditions.
  • Automatic identification of the simulation parameters required (materials, etc.).
  • Determination of the residual calibrated 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.

Modal analysis: how can Digital Image Correlation (DIC) help?

Sensor

Modal analysis is a key technique used in engineering to understand the vibratory behavior of mechanical structures. It enables us to determine the natural frequencies and modal shapes of a structure, which are crucial in ensuring that it does not resonate dangerously under specific operating conditions. Traditionally, this analysis has relied on the use of…
