Image-based meshing is the process by which 3D images (e.g., X-ray CT or laser scanning) are converted into ultra-high-resolution simulations. 3D imaging is increasingly being used in the industrial sector for inspection, non-destructive testing / evaluation (NDT/NDE) and metrology but image-based simulation is still an underutilised technique. Our aim is that the activities of IBSim-4i will facilitate a wider adoption of image-based simulation and provide a platform to discuss the cutting-edge developments in the field.
