Standardized Non-Intrusive Reduced Order Modeling Using Different Regression Models With Application to Complex Flow Problems
Artūrs Bērziņš, Jan Helmig, Fabian Key +1
In recent years, numerical methods in industrial applications have evolved from a pure predictive tool towards a means for optimization and control. Since standard numerical analys…
Combining Boundary-Conforming Finite Element Meshes on Moving Domains Using a Sliding Mesh Approach
Jan Helmig, Fabian Key, Marek Behr +1
For most finite element simulations, boundary-conforming meshes have significant advantages in terms of accuracy or efficiency. This is particularly true for complex domains. Howev…
Boundary-Conforming Finite Element Methods for Twin-Screw Extruders using Spline-Based Parameterization Techniques
Jochen Hinz, Jan Helmig, Matthias Möller +1
This paper presents a novel spline-based meshing technique that allows for usage of boundary-conforming meshes for unsteady flow and temperature simulations in co-rotating twin-scr…
Boundary-Conforming Finite Element Methods for Twin-Screw Extruders: Unsteady - Temperature-Dependent - Non-Newtonian Simulations
Jan Helmig, Marek Behr, Stefanie Elgeti
We present a boundary-conforming space-time finite element method to compute the flow inside co-rotating, self-wiping twin-screw extruders. The mesh update is carried out using the…
Fluid-structure interaction with NURBS-based coupling
Norbert Hosters, Jan Helmig, Atanas Stavrev +2
Engineering design via CAD software relies on Non-Uniform Rational B-Splines (NURBS) as a means for representing and communicating geometry. Therefore, in general, a NURBS descript…
