  • A cut finite element method for the solution of the full-potential equation with an embedded wake 

    Davari, Masud; Rossi, Riccardo; Dadvand, Pooyan; Lopez, Iñigo; Wüchner, Roland (Springer, 2019-05)
    Open Access
    Potential flow solvers represent an appealing alternative for the simulation of non-viscous subsonic flows. In order to deliver accurate results, such techniques require prescribing explicitly the so called Kutta condition, ...
  • A robust algorithm for implicit description of immersed geometries within a background mesh 

    Baumgaertner, Daniel; Wolf, Johannes; Rossi, Riccardo; Dadvand, Pooyan; Wüchner, Roland (Springer, 2018-12)
    Open Access
    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 ...
  • Contribution to the fluid-structure interaction analysis of ultra-lightweight structures using an embedded approach 

    Baumgartner, Daniel; Wolf, Johannes; Rossi, Riccardo; Wüchner, Roland; Dadvand, Pooyan (2015)
    Open Access
    Designing large ultra-lightweight structures within a fluid flow, such as inflatable hangars in an atmospheric environment, requires an analysis of the naturally occurring fluid-structure interaction (FSI). To this end ...
  • Realization of CAD-integrated shell simulation based on isogeometric B-Rep analysis 

    Teschemacher, Tobias; Bauer, Anna; Oberbichler, Thomas; Breitenberger, Micheal; Rossi, Riccardo; Wüchner, Roland; Bletzinger, Kai Uwe (Springer, 2018-12)
    Open Access
    An entire design-through-analysis workflow solution for isogeometric B-Rep analysis (IBRA), including both the interface to existing CADs and the analysis procedure, is presented. Possible approaches are elaborated for the ...
  • Towards the virtual wind tunnel 

    Larese De Tetto, Antonia; Rossi, Riccardo; Zorrilla Martínez, Rubén; Wüchner, Roland; Oñate Ibáñez de Navarra, Eugenio (2017)
    Conference report
    Restricted access - publisher's policy
    The maturity of numerical techniques both in Computational Structural and Fluid Dynamics, accompanied by the availability of affordable high-performance hardware, allows the use of virtual rapid-prototyping facilities as ...
