Contact problem modelling using the Cartesian grid Finite Element Method

Navarro Jiménez, José Manuel (Universitat Politècnica de València, 2019-07-29)

[ES] La interacción de contacto entre sólidos deformables es uno de los fenómenos más complejos en el ámbito de la mecánica computacional. La resolución de este problema requiere de algoritmos robustos para el tratamiento ...
Exact 3D boundary representation in finite element analysis based on Cartesian grids independent of the geometry

Marco Alacid, Onofre; Sevilla, R.; Zhang, Yongjie; Ródenas, J.J.; Tur Valiente, Manuel (Wiley, 2015-08)

[EN] This paper proposes a novel Immersed Boundary Method where the embedded domain is exactly described by using its Computer-Aided Design (CAD) boundary representation with Non-Uniform Rational B-Splines (NURBS) or ...
Optimization of a finite element code implemented in MATLAB. On the use of GPUs for High Performance Computing

Navarro Jiménez, José Manuel (Universitat Politècnica de València, 2015-07-17)

[EN] The Department of Mechanical and Materials Engineering has developed a 2D Finite Element code based on geometry independent Cartesian grids (cgFEM) capable of solving shape optimization problems as well as making ...
Robust h-adaptive meshing strategy considering exact arbitrary CAD geometries in a Cartesian grid framework

Marco, O.; Ródenas, J.J.; Navarro-Jiménez, J.M.; Tur Valiente, Manuel (Elsevier, 2017)

[EN] Geometry plays a key role in contact and shape optimization problems in which the accurate representation of the exact geometry and the use of adaptive analysis techniques are crucial to obtaining accurate ...
Structural Shape Optimization Based On The Use Of Cartesian Grids

Marco Alacid, Onofre (Universitat Politècnica de València, 2018-07-06)

As ever more challenging designs are required in present-day industries, the traditional trial-and-error procedure frequently used for designing mechanical parts slows down the design process and yields suboptimal designs, ...
Structural shape optimization using Cartesian grids and automatic h-adaptive mesh projection

Marco, Onofre; Ródenas, J.J.; Albelda Vitoria, José; Nadal, Enrique; Tur Valiente, Manuel (Springer-Verlag, 2017)

[EN] We present a novel approach to 3D structural shape optimization that leans on an Immersed Boundary Method. A boundary tracking strategy based on evaluating the intersections between a fixed Cartesian grid and the ...
