A Groundwater Mass Transport and Equilibrium Chemistry Model for Multicomponent Systems
TL;DR: TransQL as mentioned in this paper is a multicomponent transport model for a finite element solution, where the equilibrium interaction chemistry is posed independently of the mass transport equations, which leads to a set of algebraic equations for the chemistry coupled to the set of differential equations for mass transport.

Numerical model for radio-frequency ablation of the endocardium and its experimental validation
TL;DR: A theoretical model for the study of the radiofrequency (RF) ablation technique is presented, relying on a finite-element time-domain calculation of the temperature distribution in a block of tissue, resulting from the flow of RF (<1 MHz) electrical current.
Journal ArticleDOI
The use of lumped capacitance in the finite-element solution of heat conduction problems with phase change
TL;DR: In this paper, the authors combined the explicit enthalpy method and Pham's three-level enthalhip method to obtain a diagonal capacitance matrix, which can be used to estimate the specific heat near the phase change point.

Application of hybrid-Trefftz element approach to transient heat conduction analysis
J. Jirousek,Qing-Hua Qin +1 more
TL;DR: In this article, a hybrid-Trefftz element approach for numerical solution of transient linear heat conduction problems is presented, which discretizes the TLC equation with respect to time and then solves the resulting set of elliptic equations by the corresponding time independent hybrid Trefftz elements approach.
Numerical Algorithms in a Lagrangian Hydrocode.
TL;DR: In this paper, the numerical algorithms used in an explicit Lagrangian finite element hydrocode are described, and a comprehensive presentation of the numerical techniques used in a current production hydrocode is presented.
