Several old and new finite-element preconditioners for nodal-based spectral discretizations of −laplace(u) = f in the domain Ω=(−1,1)d (d = 2 or 3), with Dirichlet or Neumann boundary conditions, are considered and compared in terms of bothcondi ...
This paper addresses the design of a new hybrid MEMS micromotor. It gives insights on the choices, which led to the fabrication of a small 3-phases axial flux BLDC motor. The stator is developed following the almost CMOS technology rules used for MEMS manu ...
A space–time adaptive method is presented for the numerical simulation of mass transport in electroosmotic and pressure-driven microflows in two space dimensions. The method uses finite elements with large aspect ratio, which allows the electroosmotic flow ...
A numerical approach, named TransChlor, is proposed to simulate transport phenomena of various substances in concrete. This approach is a theoretical model based on finite elements and finite differences methods. The model consists of coupled nonlinear par ...
Composite materials undoubtedly belong to one of the most studied classes of materials nowadays. In order to model the behaviour of mechanical structures made of this type of materials, it is necessary to know their constitutive properties. The varieties o ...

Today, to create and to simulate a virtual anatomical version of a subject is useful in the decision process of surgical treatments. The muscular activity is one of the factors which can contribute to abnormal movements such as in spasticity or static cont ...

We develop a discretization and solution technique for elliptic problems whose solutions may present strong variations, singularities, boundary layers and oscillations in localized regions. We start with a coarse finite element discretization with a mesh s ...

Comparison between different formalisms and models is often by flattening structure and reducing them to behaviourally equivalent models e.g. automaton and Turing machine. This leads to a notion of expressiveness which is not adequate for component-based s ...

Finite element formulations are commonly used to predict stress, strain and temperature fields in metal forming. As these models have now gained robustness, an increasing attention is placed on the metallurgical evolutions associated with the thermal and m ...
