Sensitivity analysis of non-uniform rational B-splines–based finite element/boundary element coupling in structural-acoustic design

open access: yesFrontiers in Physics
For the purpose of modeling the acoustic fluid-structure interaction using direct differentiation method and conducting a structural-acoustic sensitivity analysis, a coupling approach based on the finite element method and the fast multipole boundary ...

Construction of analysis-suitable $G^1$ planar multi-patch parameterizations

open access: yes, 2017
Isogeometric analysis allows to define shape functions of global $C^{1}$ continuity (or of higher continuity) over multi-patch geometries. The construction of such $C^{1}$-smooth isogeometric functions is a non-trivial task and requires particular multi ...

Locating optimal position of artificial recharge wells in aquifer using grey wolf optimization algorithm and isogeometric numerical method

open access: yesApplied Water Science, 2022
The construction of injection wells is one of the direct methods of artificial recharge and determining their optimal location is one of the important issues that are discussed in the topics of projects related to the rehabilitation of aquifers.

BDDC Deluxe for Isogeometric Analysis [PDF]

open access: yes, 2016
The main goal of this paper is to design, analyze, and test a BDDC (Balancing Domain Decomposition by Constraints, see [12, 23]) preconditioner for Isogeometric Analysis (IGA), based on a novel type of interface averaging, which we will denote by deluxe scaling, with either full or reduced set of primal constraints.

Unstructured spline spaces for isogeometric analysis based on spline manifolds

open access: yes, 2015
Based on spline manifolds we introduce and study a mathematical framework for analysis-suitable unstructured B-spline spaces. In this setting the parameter domain has a manifold structure, which allows for the definition of function spaces that have a ...

Towards the isogeometric aero-engine

open access: yesResults in Engineering, 2023
Creating very detailed finite element models of aero-engines is a very time-consuming process especially if structured meshes have to be generated for thousands of parts.

Volumetric spline parameterization for isogeometric analysis [PDF]

open access: yesComputer Methods in Applied Mechanics and Engineering, 2020
Given the spline representation of the boundary of a three dimensional domain, constructing a volumetric spline parameterization of the domain (i.e., a map from a unit cube to the domain) with the given boundary is a fundamental problem in isogeometric analysis.

Automatic Adaptive and Targeted Localized Refinement in Transient Structural Dynamic Simulations Using the Multiresolution Finite Wavelet Domain Method

open access: yesInternational Journal for Numerical Methods in Engineering, Volume 127, Issue 1, 15 January 2026.
ABSTRACT The multiresolution finite wavelet domain method has been meticulously studied in numerous wave propagation simulations, showing excellent convergence properties and very fast computing times. The multiresolution procedure always starts with the coarse solution, and then finer solutions can be superimposed on the coarse solution until ...

IGA-based Multi-Index Stochastic Collocation for random PDEs on arbitrary domains

open access: yes, 2019
This paper proposes an extension of the Multi-Index Stochastic Collocation (MISC) method for forward uncertainty quantification (UQ) problems in computational domains of shape other than a square or cube, by exploiting isogeometric analysis (IGA ...
