Parallel Molecular Dynamics with Irregular Domain Decomposition

The spatial domain of Molecular Dynamics simulations is usually a regular box that be easily divided in subdomains for parallel processing. Recent efforts aimed at simulating complex biological systems, like the blood flow inside arteries, require the exec ...

Propagation and absorption of low frequency waves in two and three dimensional warm plasmas

Nicolas Mellet

In order to model a broader range of phenomena taking place in three-dimensional plasmas, the LEMan code has been extended to a warm formulation. As the wave propagation is strongly influenced by the parallel wave vector, special attention has been paid fo ...

Multiscale modelling of urban climate

Adil Rasheed

Climate has a direct impact on cities' energy flows due to the space conditioning (heating, cooling) needs of the buildings accommodated. This impact may be reinforced due to climate change and to the (so called) urban heat island effect. The corresponding ...

Polymorphic nodal elements and their application in discontinuous Galerkin methods

Jan Sickmann Hesthaven

In this work, we discuss two different but related aspects of the development of efficient discontinuous Galerkin methods on hybrid element grids for the computational modeling of gas dynamics in complex geometries or with adapted grids. In the first part, ...

IFS-Modeling for Feasible Freeform Timber Constructions

Yves Weinand, Ivo Stotz, Gilles Gouaty

Within the last years, architectural design has shown great interest in the design of new and complex geometries, commonly known as 'free-form' architecture. The lack of constructive feasibility of the designed architectural objects led us to consider disc ...

Innovative Manufacturing Technology for RF Passive Devices Combining Electroforming and CFRP Application

Michael Mattes

In this paper an innovative manufacturing technology is presented that combines electroforming and CFRP application and thus could be an enabling technology to achieve tuningless lightweight RF passive hardware with complex geometries. In order to demonstr ...

ORIGAMI - Folded Plate Structures, Architecture

Yves Weinand, Hans Ulrich Buri

This research proposes new methods to generate rapidly complex folded plate structures that can be built with cross laminated timber panels. Composition and dimensions of these panels as well as the possibility to mill them by Computer Numerically Controll ...

Optimal control of geodesics in Riemannian manifolds

Roland Rozsnyo

The aim of this dissertation is to solve numerically the following problem, denoted by P : given a Riemannian manifold and two points a and b belonging to that manifold, find a tangent vector T at a, such that expa(T) = b, assuming that T exists. This prob ...

High-order nodal discontinuous Galerkin particle-in-cell method on unstructured grids

Jan Sickmann Hesthaven

We present a high-order particle-in-cell (PIC) algorithm for the simulation of kinetic plasmas dynamics. The core of the algorithm utilizes an unstructured grid discontinuous Galerkin Maxwell field solver combining high-order accuracy with geometric flexib ...

High-order collocation methods for differential equations with random inputs

Jan Sickmann Hesthaven

Recently there has been a growing interest in designing efficient methods for the solution of ordinary/ partial differential equations with random inputs. To this end, stochastic Galerkin methods appear to be superior to other nonsampling methods and, in m ...
