Free and forced vibration analysis over meshes with tangled (non-convex) elements

B Prabhune, K Suresh - Computers & Structures, 2024 - Elsevier
Abstract Tangled (non-convex) elements, ie elements with negative Jacobian determinant,
can lead to erroneous results in the standard finite element method (FEM). Constructing …

On why mesh untangling may not be required

B Prabhune, K Suresh - Engineering with Computers, 2024 - Springer
Generating tangle-free high-quality hexahedral meshes is an ongoing challenge. Tangled
meshes, ie, meshes containing negative Jacobian elements, are unsuitable for finite …

B Prabhune, K Suresh - Computational Mechanics, 2024 - Springer
This paper presents an isoparametric tangled finite element method (i-TFEM) method for
handling tangled high order/curvilinear meshes. Tangled elements, ie elements with …

[图书][B] Tangled Finite Element Methods for Handling Negative Jacobian Elements

BC Prabhune - 2023 - search.proquest.com
Finite element method (FEM) is a well-established technique for numerical analysis.
Meshing is a critical step in FEM and is estimated to take over 80% of the overall analysis …
