Integrating CAD and Numerical Analysis: 'Dirty Geometry' handling using the Finite Cell Method
Benjamin Wassermann, Stefan Kollmannsberger, Shuohui Yin +2
This paper proposes a computational methodology for the integration of Computer Aided Design (CAD) and the Finite Cell Method (FCM) for models with "dirty geometries". FCM, being a…
From geometric design to numerical analysis: A direct approach using the Finite Cell Method on Constructive Solid Geometry
Benjamin Wassermann, Stefan Kollmannsberger, Tino Bog +1
During the last ten years, increasing efforts were made to improve and simplify the process from Computer Aided Design (CAD) modeling to a numerical simulation. It has been shown t…
A design-through-analysis approach using the Finite Cell Method (ECCOMAS Congress 2016)
Benjamin Wassermann, Tino Bog, Stefan Kollmannsberger +1
Modern 3D Computer-Aided-Design (CAD) systems use mainly two types of geometric models. Classically, objects are defined by a Boundary Representation (B-Rep), where only the object…
A high-performance interactive computing framework for engineering applications
Jovana Knežević, Ralf-Peter Mundani, Ernst Rank
To harness the potential of advanced computing technologies, efficient (real time) analysis of large amounts of data is as essential as are front-line simulations. In order to opti…
Dynamic load balancing strategies for hierarchical p-FEM solvers
Ralf-Peter Mundani, Alexander Düster, Jovana Knežević +2
Equation systems resulting from a p-version FEM discretisation typically require a special treatment as iterative solvers are not very efficient here. Applying hierarchical concept…
Computational steering of complex flow simulations
Atanas Atanasov, Hans-Joachim Bungartz, Jérôme Frisch +4
Computational Steering, the combination of a simulation back-end with a visualisation front-end, offers great possibilities to exploit and optimise scenarios in engineering applica…
