Simulation correlation with Abaqus: how far we’ve come in linking a solver to our software environment
Need to perform a correlation between an Abaqus simulation model and measurements automatically? Whether it is by developing a Python script, actually using the C++ API or developing our parsers, we have experimented a lot with reading and writing formats related to this solver, whether it is to correlate displacement or deformation fields or simply…
Mechanical regularization in EikoTwin DIC
In EikoTwin DIC, the measurement of displacement fields is performed on the simulation mesh. However, as this mathematical problem is by nature ill-posed, a mechanical regularization parameter allows the user to add mechanical conditions to the field measurements. Contrary to most digital image correlation software, at EikoSim, we have chosen to use a mechanical “filter”.…
Digital image correlation for crack measurement
In the context of crack propagation tests on composite materials, digital image correlation provides a wealth of useful information for characterizing crack advance and even the GIc. Case study from Safran. This work is part of Paul Nicolino’s engineering internship at EikoSim, who graduated from INSA Lyon in 2021 in Mechanical Engineering. The problem: highly…

Simulation validation in Excel, it’s over!
By Florent Mathieu, Ceo of EikoSim Ever wondered why you have to perform simulation validation of strain gauges in Excel ? In order to build more confidence in more refined simulation models, simulation models have to be backed up by a lot more real-world data, in order to avoid large design margins: teams now have…
EIKOSIM BRIDGES THE GAP BETWEEN TESTS AND SIMULATIONS
By Elisa Perozzi, Strategic & Digital Marketing Manager at EikoSim EikoSim is committed to reducing the gap between tests and simulation, by developing and transmitting to its customers the use of innovative tools for the validation of their numerical simulations. Thanks to its expertise and its close link with the LMT research laboratory (ENS Paris-Saclay), EikoSim…
Safran Aircraft Engines trusts EikoSim with EikoTwin
Julien Schneider is an expert at the Composites Industrial Center of Excellence at Safran Aircraft Engines, and he tells us about his experience with our software EikoTwin. What is EikoTwin? The EikoTwin software allows to implement a test/calculation dialogue during the development of industrial mechanical products. Based on innovative image processing technologies, EikoTwin aims at…
Digital image correlation for automotive structures
Context In the context of monitoring large-scale production of automotive parts, many parts are subjected to repeated tests to ensure their integrity once they are put into service. Thus, the test that we address in this paper is dedicated to the “gust of wind” tests of an opening structure (see Figure 1). Loading tests on…
Thermal plugins from the EikoTwin suite
In order to meet the specific needs of customers and to extend the use of the EikoTwin software suite to other fields of activity, EikoSim has developed two new optional plugins: the DIC and DT thermal plugins. As their names suggest, DIC thermal plugin can be used in EikoTwin DIC software, and DT thermal plugin…
