A robust algorithm for implicit description of immersed geometries within a background mesh
Autor: Daniel Baumgärtner, Johannes Wolf, Riccardo Rossi, Pooyan Dadvand, Roland Wüchner
Publikováno v: Advanced Modeling and Simulation in Engineering Sciences, Vol 5, Iss 1, Pp 1-40 (2018)
Abstract The paper presents a robust algorithm, which allows to implicitly describe and track immersed geometries within a background mesh. The background mesh is assumed to be unstructured and discretized by tetrahedrons. The contained geometry is a

Realizing CoSimulation in and with a multiphysics framework
Autor: A. Ghantasala, K. Bletzinger, P. Bucher, Pooyan Dadvand, Roland Wüchner
Publikováno v: Scopus-Elsevier
Simulating coupled problems using a multiphysics framework is different from the classical approach using dedicated coupling tools. It can have several advantages such as reduced memory footprint or more efficient communication between the involved s

Creating a highly parallelizable code is a challenge specially for Distributed Memory Machines (DMMs). Moreover, algorithms and data structures suitable for these platforms can be very different from the ones used in serial code. For this reason, man

An efficient edge-based level set finite element method for free surface flow problems
Autor: Pooyan Dadvand, Eugenio Oñate, Antonia Larese, Riccardo Rossi
Publikováno v: International Journal for Numerical Methods in Fluids. 71:687-716
We present an efficient technique for the solution of free surface flow problems using level set and a parallel edge-based finite elementmethod. An unstructured semi-explicit solution scheme is proposed. A custom data structure, obtained by blending
