Multisymplectic Lie group variational integrator for a geometrically exact beam in R-3

Tudor Ratiu, François Gay-Balmaz, François Marie Alain Demoures

In this paper we develop, study, and test a Lie group multisymplectic integrator for geometrically exact beams based on the covariant Lagrangian formulation. We exploit the multisymplectic character of the integrator to analyze the energy and momentum map ...

FPM SIMULATIONS OF A HIGH SPEED WATER JET VALIDATION WITH CFD AND EXPERIMENTAL RESULTS

François Avellan, Ebrahim Jahanbakhsh, Christian Vessaz

The present paper reports the development of Finite Particle Method (FPM) in the framework of a high-speed water jet simulation. The FPM kernel is used to improve the consistency of standard SPH for non-uniform particle distribution. The time integration i ...

Mean-square A-stable diagonally drift-implicit integrators of weak second order for stiff Itô stochastic differential equations

Assyr Abdulle, Gilles Vilmart

We introduce two drift-diagonally-implicit and derivative-free integrators for stiff systems of It stochastic differential equations with general non-commutative noise which have weak order 2 and deterministic order 2, 3, respectively. The methods are show ...

Weak second order explicit stabilized methods for stiff stochastic differential equations

Assyr Abdulle, Gilles Vilmart

We introduce a new family of explicit integrators for stiff Ito stochastic differential equations (SDEs) of weak order two. These numerical methods belong to the class of one-step stabilized methods with extended stability domains and do not suffer from th ...

Foil-to-foil interconnection of capacitive humidity sensors using electrically conductive adhesives

Nico de Rooij, Danick Briand

The present study presents the development and comparison of two foil-to-foil lamination and interconnection methods of foil-based capacitive humidity sensors. The first method uses confined anisotropic conductive adhesive (ICA) in laser ablated vias throu ...

Isogeometric Analysis for an earthquake simulation

Christoph Jäggli

We consider Isogeometric Analysis to simulate an earthquake in a two dimensional model of a sinusoidal shaped valley. We analyze two different time integration schemes, namely the Generalized- and the Leap-Frog methods. Solving a wave propagation problem l ...

Thermodynamic analysis, energy integration and flowsheet improvement of a methanol absorption acid gas removal process

François Maréchal, Emanuele Martelli, Manuele Gatti

This paper analyses the thermodynamic performance and proposes different energy integration schemes for a methanol absorption based acid gas removal process, namely the Rectisol® process specifically designed for the selective removal of H2S and CO2 from c ...

Time accurate partitioned algorithms for the solution of fluid-structure interaction problems in haemodynamics

Fabio Nobile, Christian Vergara

In this work we deal with the numerical solution of the fluid-structure interaction problem arising in the haemodynamic environment. In particular, we consider BDF and Newmark time discretization schemes, and we study different methods for the treatment of ...

KUL and EPFL cooperation on numerical integration of Sommerfeld integrals.

Juan Ramon Mosig, Ruzica Golubovic

This paper reports the result of the cooperation between KUL and EPFL on the numerical integration of Sommerfeld integrals (SI). Each institution is well-known for developing specific techniques suited for the evaluation of SI: double-exponential quadratur ...

High weak order methods for stochastic equations based on modified equations

Assyr Abdulle, Gilles Vilmart, David Cohen

Inspired by recent advances in the theory of modified differential equations, we propose a new methodology for constructing numerical integrators with high weak order for the time integration of stochastic differential equations. This approach is illustrat ...
