The FEM data generator presented in this paper is used to generate quasi-automatically or automatically the basic data for 3-d or 2-d finite element analysis of engineering projects

such as element nodal connections

material parameters

nodal coordinates

restrained boundary conditions

and the information of applied load. With the symbol-identified input data system and the concept of interpolation function of isoperimetric element

this data generator deals with regular meshes

irregular meshes

and their arbitrary combination in unified routine and the same way to input data

which is available to any kind of elements and convenient to users. The work principle of this data generator and the features of corresponding computer routines are described in detail.
