In this talk we consider shape optimization based on the approach " first
discretize then optimize". The starting point for the considerations is a
physical application which leads to a shape optimization problem of electro-
magnets. First, we have to find a geometry representation as B-spline surface
and specify the design variables. The next step is the discretization which
is, as already indicated in the title, done by means of isogeometric analysis.
Moreover, we perform a sensitivity analysis on the discrete level. Finally,
numerical results are presented.
