Finite element modeling method and computer storage medium

Abstract

The invention relates to a finite element modeling method and a computer storage medium, and belongs to the field of computer-aided engineering. The method comprises the following steps: grouping a plurality of input geometric objects, respectively carrying out grid generation processing to obtain a surface grid corresponding to each group of geometric objects, and respectively carrying out error repair processing on the surface grid corresponding to each group of geometric objects to obtain an independent surface grid corresponding to each group of geometric objects; carrying out compatibility processing on all the independent surface grids to obtain a preliminary surface grid system, carrying out grid re-division processing on the preliminary surface grid system to obtain a surface grid system, and carrying out feature extraction on the surface grid system to obtain feature information; and establishing a three-dimensional finite element model according to the surface grid system and the feature information. By means of the method, rapid finite element modeling of the multi-project object coupling system can be achieved, and the efficiency and the function integration degree of the whole finite element modeling process are effectively improved.
