Parameter-free, weak imposition of Dirichlet boundary conditions and coupling of trimmed patches
We present a parameter-free domain sewing approach for lowas well as high-order finite elements. Its final form contains only primal unknowns, i.e., the approach does not introduce additional unknowns at the interface. Additionally, it does not involve problem dependent parameters which require an estimation. The presented approach is symmetry-preserving, i.e. the resulting discrete form of an ...

متن کاملWeak Dirichlet Boundary Conditions for Wall-Bounded Turbulent Flows
In turbulence applications, strongly imposed no-slip conditions often lead to inaccurate mean flow quantities for coarse boundary-layer meshes. To circumvent this shortcoming, weakly imposed Dirichlet boundary conditions for fluid dynamics were recently introduced in [4]. In the present work, we propose a modification of the original weak boundary condition formulation that consistently incorpo...
متن کاملStable Isogeometric Analysis of Trimmed Geometries
We explore extended B-splines as a stable basis for isogeometric analysis with trimmed parameter spaces. The stabilization is accomplished by an appropriate substitution of Bsplines that may lead to ill-conditioned system matrices. The construction for non-uniform knot vectors is presented. The properties of extended B-splines are examined in the context of interpolation, potential, and linear ...
متن کاملVery weak estimates for a rough Poisson-Dirichlet problem with natural vertical boundary conditions
This work is a continuation of [3]; it deals with rough boundaries in the simplified context of a Poisson equation. We impose Dirichlet boundary conditions on the periodic microscopic perturbation of a flat edge on one side and natural homogeneous Neumann boundary conditions are applied on the inlet/outlet of the domain. To prevent oscillations on the Neumann-like boundaries, we introduce a mic...
