Annotation: Tree-dimensional numerical scheme is modified for modeling of mechanical behavior of thin-shell construction with complex geometry. The model is based on the variational statement of the quasi-static problem of solids mechanics. Calculation methods is based on the usage of the tetrahedral finite different mesh and have a better convergence character compared to scheme based on the approximation of space derivatives with spatial rectangular grid.
