IG-LSPIA: Least Squares Progressive Iterative Approximation for Isogeometric Collocation Method
Mathematics, 2023 The isogeometric collocation method (IGA-C), which is a promising branch of isogeometric analysis (IGA), can be considered fitting the load function with the combination of the numerical solution and its derivatives.

Mortar Method With Interpolative Mapping Displacement for Nonmatching Mesh Problems
International Journal for Numerical Methods in Engineering, Volume 127, Issue 17, 15 September 2026.ABSTRACT In this paper, an interpolative mapping mortar method (IM‐mortar) is proposed for nonmatching finite element meshes. Displacement continuity is enforced weakly using a Lagrange multiplier field. An intermediate frame is introduced, on which the interface displacement field is reconstructed from the adjoining bodies through interpolative ...

Optimally refined isogeometric analysis
Procedia Computer Science, 2017 Performance of direct solvers strongly depends upon the employed discretization method. In particular, it is possible to improve the performance of solving Isogeometric Analysis (IGA) discretizations by introducing multiple C-continuity hyperplanes that act as separators during LU factorization [8]. In here, we further explore this venue by introducing

MATHICSE Technical Report : Biomembrane modeling with Isogeometric Analysis [PDF]
We consider the numerical approximation of lipid biomembranes, including red blood cells, described through the Canham-Helfrich model, according to which the shape minimizes the bending energy under area and volume constraints.

International Journal for Numerical Methods in Engineering, Volume 127, Issue 16, 30 August 2026.ABSTRACT This paper presents a study on multi‐scale modelling of progressive damage model in laminated composites using shell finite elements, with considerations for the effects of manufacturing defects. The approach utilises second‐order homogenisation with 5‐parameter shell formulation to capture the effects of complex sub‐structural geometry and ...
