A GEOMETRIC PROCESSING WORKFLOW FOR TRANSFORMING REALITY-BASED 3D MODELS IN VOLUMETRIC MESHES SUITABLE FOR FEA [PDF]

The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2017
Conservation of Cultural Heritage is a key issue and structural changes and damages can influence the mechanical behaviour of artefacts and buildings. The use of Finite Elements Methods (FEM) for mechanical analysis is largely used in modelling stress ...

Parameterized Modeling of Blended Wing Body Aircraft Based on Multi-Scale CST Method [PDF]

Hangkong bingqi
In the parameterized modeling of blended wing body aircraft, the commonly used CST method has weak local deformation control capability, while the Non-Uniform Rational B-Splines(NURBS)method has the problem of too many global parameters.

The crucial role of meshing in computational fluid dynamics simulations for organic geometries in paleobiology: Describing fluid dynamics performance through best practices

Methods in Ecology and Evolution, Volume 16, Issue 10, Page 2170-2194, October 2025.
Abstract Computational fluid dynamics (CFD) has become an essential tool for studying fluid interactions in biological systems. While widely used in engineering, its application in the natural sciences, particularly in paleobiology, remains limited due to the challenges of meshing complex organic geometries.

Simulating and correcting the pileup effect in deep‐silicon photon‐counting CT

Medical Physics, Volume 52, Issue 8, August 2025.
Abstract Background Photon‐counting computed tomography (CT) bears promise to substantially improve spectral and spatial resolution. One reason for the relatively slow evolution of photon‐counting detectors in CT—the technology has been used in nuclear medicine and planar radiology for decades—is pulse pileup, that is, the random staggering of pulses ...
