System Introduction:

The EikoTwin DIC simulation design comparison verification system is a highly contactless 3D full-field optical strain analysis system introduced by Beijing Qiaoze in 2020, consisting of hardware such as computers and cameras, and the EikoTwin software analysis system. This system has made many improvements based on traditional DIC measurement systems, using FEM simulation models as a benchmark for digital image correlation processing, allowing FEM simulation data to be directly compared with measured strain data on the same platform. The provider of this system, EikoSim, is a software startup company in France, whose CEO FLORENT MATHIEU and Chief Technology Officer Renaud Gras are both PhDs in mechanics. From 2009 to 2015, they worked with Pr. Hild and Pr. Roux at the renowned European mechanics laboratory 'LMT Cachan', jointly committed to the research and development of DIC measurement technology (Pr. Hild and Pr. Roux are leading figures in DIC strain measurement technology in the mechanical industry). After EikoSim was established in France in 2016, FLORENT MATHIEU and Renaud Gras led their entire team to actively explore and practice in the application of DIC measurement technology. As a result, EikoSim's DIC products incorporate relatively advanced DIC technology measurement solutions. For example, the results of analyzing displacement, strain, and other data collected through DIC software can be directly compared with FEM simulation models without gaps, and even the FEM simulation model can be repaired and improved based on experimental data, making users' work faster and more effective, reducing the number of experiments conducted in reality, and ensuring or completing work goals ahead of schedule. Currently, EikoSim's DIC strain measurement system is favored by users in industries such as aerospace, defense, automotive, and research institutions abroad, such as ARIANE GROUP (Arianespace in France), AIR BUS (Airbus in Europe), SAFRAN (Safran Group in France), and CETIM (French Mechanical Industry Technology Center), all of which are loyal users of EikoSim's DIC strain measurement system.

EikoTwin-DIC Optical Full-Field Measurement Solution:
* Image processing based on finite element mesh
* Automatic calibration around the mesh
* Multi-view (no technical limit on the number of cameras)
The EikoTwin DIC software system requires image files and FEM model files in a matching format, such as:
1) Format for importing images taken by visible light cameras: .tif, .png, .jpg, .bmp
2) Format for importing infrared camera images: .mat(-v.4)
3) Format for imported MESH models:
▪ Abaqus format (.inp): compatible with any type of linear and nonlinear elements and all element type formats (from version 2018)
▪ Samcef format (.dat): compatible with Tri/Tetra, Quad/Hex, and Wedge types of linear and nonlinear elements, as well as the following format
written in 'AEL' type: 'I element number FRAME local landmark number'
▪ Gmsh format (.msh): compatible with any version up to 4.1, except 4.0
▪ HyperWorks format (.h3d)
