We propose a convenient methodology for the modeling and analysis of aircraft compressor
blades. To meet this goal, IsoGeometric Analysis is put to good use, as it allows for an exact …

To accurately capture the dynamic responses of flexible multibody systems with complex
geometric shapes or with contact and collision problems, extremely fine meshes have to be …

Conventional two-field mortar methods have master/slave bias and need special treatments
for the cross corner problem. In this work, we present a three-field dual mortar method, which …

Abstract We study Dual–Primal Isogeometric Tearing and Interconnecting (IETI-DP) solvers
for non-conforming multi-patch discretizations of a generalized Poisson problem. We realize …

A method for three-dimensional non-matching interface treatment with a virtual gap element
is developed. When partitioned structures contain curved interfaces and have different brick …

The railgun's armature and rail are in high-speed sliding electrical contact, and there is a
velocity skin effect regarding electromagnetic field distribution. Under this effect, current …

Tying non-matching meshes is needed in many instances of finite element modeling.
Multiple techniques have been proposed in the literature to accomplish the correct …

Abstract The Domain Interface Method (DIM) is extended in this contribution for the case of
mixed fields as encountered in multiphysics problems. The essence of the non-conforming …

An independent medium surface is introduced to extend the mortar method from a two-field
variational principle to a three-field version. The Lagrange multipliers are discretized by …

Abstract Dual-Primal Isogeometric Tearing and Interconnecting (IETI-DP) methods are non-
overlap** domain decomposition techniques for solving large linear systems of algebraic …
