The work purpose: a systematic (constant) clas-sification of finite elements for designation unity, the exclusion of repeated investigations and results dupli-cating. Methods. A decimal nomenclature dncmkot code for finite elements is offered. It is based on the geometry and structure presentation of node coordinates by integral (whole) parame-ters: d – dimensionality, n – nodes number, c – parameter defining a structure of node coordinates, for example, coordinates number in a node, m – number of interpolation polynomials of an element. For more complicated elements the application of additional parameters is possible. To this there are added of an element physical functional: k – order of senior derivative upon which depends a sub-integral expression of a physical functional, t – additional pa-rameter-type. Results. There is offered an algorithm allowing calculating functions of an element form, its matrix of rigidity and others through dncmkot code. The corres-pondence of the finite elements set from ANSYS soft-ware to their codes according to the classification offered is shown. The examples of new elements creation on the basis of the classification offered are presented. Conclusion: the classification offered allows describing unambiguously existing finite elements and also creating in an automated way new ones according to dncmkot code.
