Efficient Distance Computation in the Isogeometric Analysis


When assembling the system matrices of the boundary element method, the distance between two objects must be determined in an efficient way. At the moment, a very rudimentary but fast method is used. However, one could also use geometric quantities such as the control points and the knot insertion algorithm from isogeometric analysis, as shown below, to do this more accurately. The implementation is carried out in the C++ library Bembel, see www.bembel.eu.
