The aim of the paper is to show that the isogeometric Boundary Element Method (isoBEM) has advantages over other numerical methods when applied to problems in potential flow. The problems presented here range from the flow past an obstacle to confine

In this work a novel approach is presented for the isogeometric Boundary Element analysis of domains that contain inclusions with different elastic properties than the ones used for computing the fundamental solutions. In addition the inclusion may e

In this work a novel approach is presented for the Boundary Element analysis of underground excavation problems. Firstly, Non-Uniform Rational B-Spines (NURBS) are used for the description of the geometry and for the approximation of the unknowns. Th

This is a sequel to a previous paper (Beer et al., 2017) [1] where a novel approach was presented to the 2-D Boundary Element analysis of steady incompressible viscous flow. Here the method is extended to three dimensions. NURBS basis functions are u

The paper outlines some recent developments of the boundary element method (BEM) that makes it more user friendly and suitable for a realistic simulation in geomechanics, especially for underground excavations and tunnelling. The innovations refer to

The BEM relies on the availability of fundamental solutions of the governing differential equations, which are only available for homogeneous domains. As this would restrict the practical application of the method, we explore here the possibility of

The BEM is ideally suited for applications in geomechanics because it can handle infinite domain problems without truncation. This chapter shows how the theory outlined so far can be applied to practical problems, in this case the simulation of under

We provide insight into the representation of geometric objects in CAD. In particular, this chapter covers the generalisation of B-splines to NURBS, the interaction of control points and their patches, and the concept of trimmed surfaces. After prese
