A novel updating modelling methodology for free-form surface modifications in the early stages of design [PDF]
, 2003 The paper describes the first implementation of a method in which an initial CAD model is updated from a physical model. The method is based on image-mapping in which an initial CAD model is updated from images of a soft rapid prototype model (RPM) which

Isogeometric Analysis and Harmonic Stator-Rotor Coupling for Simulating Electric Machines
, 2017 This work proposes Isogeometric Analysis as an alternative to classical finite elements for simulating electric machines. Through the spline-based Isogeometric discretization it is possible to parametrize the circular arcs exactly, thereby avoiding any ...

IGS: an IsoGeometric approach for Smoothing on surfaces
, 2016 We propose an Isogeometric approach for smoothing on surfaces, namely estimating a function starting from noisy and discrete measurements. More precisely, we aim at estimating functions lying on a surface represented by NURBS, which are geometrical ...

One‐Shot Method for Computing Generalized Winding Numbers
Computer Graphics Forum, Volume 44, Issue 5, August 2025.Abstract The generalized winding number is an essential part of the geometry processing toolkit, allowing to quantify how much a given point is inside a surface, even when the surface has boundaries and noise. We propose a new universal method to compute a generalized winding number, based only on the surface boundary and the intersections of a single ...

International Journal for Numerical Methods in Engineering, Volume 126, Issue 14, 30 July 2025.ABSTRACT The article tackles the challenge of effective modeling and simulation of large mechanical structures exhibiting numerous local complex behaviors, as encountered with spot welds in automotive crash numerical analysis. To address this challenge, we propose a nonintrusive local/global coupling strategy, where the local model is a neural network ...

Isogeometric analysis applied to frictionless large deformation elastoplastic contact [PDF]
, 2013 This paper focuses on the application of isogeometric analysis to model frictionless large deformation contact between deformable bodies and rigid surfaces that may be represented by analytical functions. The contact constraints are satisfied exactly with
