The subject of this article concerns Isogeometric Analysis (IGA) as a new formulation within Finite Element Method [1]. Motivation for this new approach was presented together with theoretical foundations of the method. Special focus was put on the new concept of element and new geometry data interpretation in terms of analysis. In this paper the problems of implementation of the IGA method is discussed. Existing FEM codes do not allow for easy adaptation of the IGA. Currently there are three packages dedicated to the IGA: GeoPDEs, Abaqus plugin and Rhino-Grasshoper-Matlab, [3, 2, 4]. Geometry and mesh transfer from Rhino software with Grasshopper plug-in was also described in this paper. Finally, authors conclusions concerning new approach to finite element method were presented.
