This special issue will focus on the topic to “unfitted” techniques in computational mechanics. Unfitted techniques, also known as “embedded” or “immersed” approaches, represent a hot topic in Computational Mechanics due to their potential in lifting some of the outstanding restrictions of current techniques.


  1. 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 tetrahedr...

  2. 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 elabo...

  3. The definition of the surface plays an important role in the solution of contact problems, as the evaluation of the contact force is based on the measure of the gap between the solids. In this work three diffe...

  4. We consider a cut isogeometric method, where the boundary of the domain is allowed to cut through the background mesh in an arbitrary fashion for a second order elliptic model problem. In order to stabilize th...
