ON DEVELOPMENT OF THE INTERACTIVE DESIGN TOOL BASED ON ISOGEOMETRIC ANALYSIS

open access: yesActa Polytechnica CTU Proceedings, 2017
Isogeometric analysis is a new concept of Finite element method which has been proposed to bridge the gap between the CAD systems and the FEM solvers. In Isogeometric analysis, the same basis functions, typically splines or NURBS, are used for geometry ...

A Comparative Study of Several Classical, Discrete Differential and Isogeometric Methods for Solving Poisson’s Equation on the Disk

open access: yesAxioms, 2014
This paper outlines and qualitatively compares the implementations of seven different methods for solving Poisson’s equation on the disk. The methods include two classical finite elements, a cotan formula-based discrete differential geometry approach and

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.

Stability and convergence of high-order Isogeometric discretizations for acoustic wave problems [PDF]

open access: yes, 2019
In the last decades, an increasing number of works focused on the simulation of acoustic waves propagation in geophysics in order to improve the low-order accuracy of finite difference or finite element methods.

Isogeometric analysis for turbulent flow [PDF]

open access: yesMathematics and Computers in Simulation, 2018
The article is devoted to the simulation of viscous incompressible turbulent fluid flow based on solving the Reynolds averaged Navier-Stokes (RANS) equations with different k-omega models. The isogeometrical approach is used for the discretization based on the Galerkin method.
