Coping with the so called high Weissenberg number problem (HWNP) is a key focus of research in computational rheology. By numerically simulating viscoelastic flow a breakdown in convergence often occurs for different ...

Phase interfaces in melting and solidification processes are strongly affected by the presence of convection in the liquid. One way of modeling their transient evolution is to couple an incompressible flow model to an...

Thermoforming is a process for the cheap mass-production of thin-walled plastic parts. A sheet of plastic is heated for increased deformability, and then deformed by overpressure into a mold with the end product’s sh...

Within the framework of this study, two hybrid LES/RANS turbulence models, namely the limited numerical scales model (LNS) and the very large eddy simulation model (VLES), are investigated for the aeroacoustic simulat...

We study linear systems of equations arising from a stochastic Galerkin finite element discretization of saddle point problems with random data and its iterative solution. We consider the Stokes flow model with random...

Many simulations in computationalengineering suffer from slow convergence rates of their linear solvers. This is also true for the Finite Pointset Method (FPM), which is a Meshfree Method used in computational Fluid ...

We consider the optimal control of fluid-structure interaction (FSI) problems. In order to apply a multilevel optimization algorithm, we introduce a reduced order model using proper orthogonal decomposition (POD). The...

This book comprises the proceedings of the 4th International Conference on computationalengineering (ICCE 2017), held in Darmstadt, Germany on September 28-29, 2017. The conference is intended to provide an interdisciplinary meeting place for researchers and practitioners working on computational methods in all disciplines of engineering, applied mathematics and computer science. The aims of the conference are to discuss the state of the art in this challenging field, exchange experiences, develop promising perspectives for future research and initiate further cooperation. computationalengineering is a modern and multidisciplinary science for computer-based modeling, simulation, analysis, and optimization of complex engineering applications and natural phenomena. The book contains an overview of selected approaches from numerics and optimization of Partial Differential Equations as well as uncertainty quantification techniques, typically in multiphysics environments. Where possible, application cases from engineering are integrated. The book will be of interest to researchers and practitioners of computationalengineering, Applied Mathematics, engineeringsciences and Computer science.
