Subregion Boundary Element Method

JSME international journal. Ser. A, Mechanics and material engineering, 1993
The system of equations for each subregion, which is derived from the boundary integral equation, is transformed to an equation similar to the stiffness equation of the finite element method. The global equation is made by the superposition of these matrix equations.

A FEM-Green Approach for Magnetic Field Problems with Open Boundaries

Mathematics, 2021
A new finite element method/boundary element method (FEM/BEM) scheme is proposed for the solution of the 2D magnetic static and quasi-static problems with unbounded domains. The novelty is an original approach in the treatment of the outer region.

Hybrid finite difference/finite element immersed boundary method [PDF]

, 2017
The immersed boundary method is an approach to fluid-structure interaction that uses a Lagrangian description of the structural deformations, stresses, and forces along with an Eulerian description of the momentum, viscosity, and incompressibility of ...

Weak imposition of Signorini boundary conditions on the boundary element method [PDF]

, 2020
We derive and analyse a boundary element formulation for boundary conditions involving inequalities. In particular, we focus on Signorini contact conditions.

Clinical Insights Into Hypercalcemia of Malignancy in Childhood

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Hypercalcemia of malignancy (HCM) is a rare but life‐threatening metabolic emergency in children that occurs in less than 1% of pediatric cancer cases, with a reported incidence ranging from 0.4% to 1.0% across different studies. While it is observed in 10%–20% of adult malignancies, pediatric HCM remains relatively uncommon.
