EikoTwin DIC by EikoSim 

A Bridge Between Simulation and Test

EikoTwin DIC allows image processing (digital image correlation) based on the finite element (FE) mesh of your simulation.

DIC is an image processing technique that allows users to measure displacements and strains of a structure during mechanical testing. Compared to strain gages and extensometers, DIC drastically increases the amount of information gathered and the ability for the user to understand the mechanical behavior of their structure. But traditional DIC software produce a measurement of displacement and strains of a cloud of points. Thus, users often have a hard time comparing experimental data with simulation results. EikoTwin DIC is simulation-oriented, which means these displacements and strains are directly measured from the images on the FE mesh. As a result, EikoTwin DIC directly compares these deformations to those predicted by numerical simulations.

Through a single test, EikoTwin DIC users are able to understand immediately how to improve their simulations, thus avoiding trial and error and wasting time.

Why EikoTwin DIC?

Direct Test Simulation Comparison

The test results are measured on the FE mesh, making it directly usable by the simulation engineer.

Large Measurement Area

Measurement data is full-field instead of pointwise, making result analysis more comprehensive and robust.

Direct Export to Altair Simulation Tools

Results can be directly exported to be used in Altair® HyperWorks® for post-processing.

Key Features

Full-field Measurements

Displacements, strains, and correlation residuals (at pixel scale) are measured directly on the surface of the part.

No Graphic

Multi-camera View

There is no technical limit to the numbers of cameras, allowing the user to measure displacements and strains all around the FE mesh.

No Graphic

Virtual Sensors

Virtual displacement sensors, extensometers, and strain gauges can be positioned anywhere to compare DIC results, physical sensors, and simulations.
