A Finite Element Method is a constructive procedure for approximating a weak solution by using a linear combination of basis functions. These basis functions are chosen from a finite dimensional subspace and are used to create a finite element approximation of the weak solution. This method is comm...
This book gives an introduction to the finite element method as a general computational method for solving partial differential equations approximately. Our approach is mathematical in nature with a strong focus on the underlying mathematical principles, such as approximation properties of piecewise polynomi...
“I first heard the words ‘the Finite Element Method” in 1967—which changed my life. I started to read everything that was available and convinced my boss to start the Finite Element Method Development Group, which he did. Dr. Henno Allik was Group Leader,...

we will aim at developing the necessary tools for the student to model physical problems using finite element method as well as programming simple problems of structure mechanics and some coupled problems. To achieve that aim, simple examples will be presented and the MATLAB code used to solve th...

This family includes an improved version of the divergence-free finite element method used in the PLTMG code. Numerical results show that the new method is able to compute strikingly accurate solutions on coarse meshes. An analysis of the use of Slotboom variables shows that they are ...
Some unexpected behaviours of PTW/Nucletron well-type ionization chambers have been discovered. A significant undesired detection volume is present in the region surrounding the electrical terminals. A finite-element code has been used to compute electrical fields in this region, and it showed that th...
