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.

Modal analysis validation – in practice
In a recent post, we mentioned how DIC can be used for modal analysis validation by comparing the measured field with a finite element simulation. A practical exercise was proposed to us by INTES: how to export results to a simulation pre-post, in this case that of the PERMAS software? In this case, we have…
Building simulation credibility: the validation of Ariane 6’s Dual Launch Structure
Ensuring the credibility of simulation models is a concern in all fields of engineering.

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