摘要：

Ways of nodal loads generating are considered. It is shown that the method based on the use of the shape function most adequately describes the volume forces spatial distribution. Based on this approach, the novel code NFORCE allows the calculation of nodal loads for conventional types of 2D and 3D finite elements. The results of the program verification are presented.
