  In the paper a recent enhancement to the open source package SfePy (Simple
Finite Elements in Python, http://sfepy.org) is introduced, namely the addition
of another numerical discretization scheme, the isogeometric analysis, to the
original implementation based on the nowadays standard and well-established
numerical solution technique, the finite element method. The isogeometric
removes the need of the solution domain approximation by a piece-wise polygonal
domain covered by the finite element mesh, and allows approximation of unknown
fields with a higher smoothness then the finite element method, which can be
advantageous in many applications. Basic numerical examples illustrating the
implementation and use of the isogeometric analysis in SfePy are shown.
