Finite Element of Linear Viscoelastic Solids [PDF]
Engineering and Technology Journal, 2005 A linear thermoviscoelastic material model, whose basis is an incremental constitutive equation that takes complete strain and temperature histories into account, is derived in finite element code " FEVES "(finite element of scoelastic solids).

Compatible finite element methods for numerical weather prediction [PDF]
, 2014 This article takes the form of a tutorial on the use of a particular class of mixed finite element methods, which can be thought of as the finite element extension of the C-grid staggered finite difference method.

Unified Framework for Finite Element Assembly
, 2009 At the heart of any finite element simulation is the assembly of matrices and vectors from discrete variational forms. We propose a general interface between problem-specific and general-purpose components of finite element programs.

An interactive graphics system to facilitate finite element structural analysis [PDF]
, 1973 The characteristics of an interactive graphics systems to facilitate the finite element method of structural analysis are described. The finite element model analysis consists of three phases: (1) preprocessing (model generation), (2) problem solution ...

Analysis of a high order Trace Finite Element Method for PDEs on level set surfaces
, 2016 We present a new high order finite element method for the discretization of partial differential equations on stationary smooth surfaces which are implicitly described as the zero level of a level set function.

Kriging-Based Finite Element Method: Element-By-Element Kriging Interpolation
Civil Engineering Dimension, 2009 An enhancement of the finite element method with Kriging shape functions (K-FEM) was recently proposed. In this method, the field variables of a boundary value problem are approximated using ‘element-by-element’ piecewise Kriging interpolation (el-KI ...

Finite-Element Modelling of Biotransistors
Nanoscale Research Letters, 2010 Current research efforts in biosensor design attempt to integrate biochemical assays with semiconductor substrates and microfluidic assemblies to realize fully integrated lab-on-chip devices. The DNA biotransistor (BioFET) is an example of such a device.
