The essence of the main problems arising at narrowgaps models splitting on final elements is opened. Advantages and disadvantages of program modules at work withsmall gaps are given. Solutions of the difficulties arising at final-element modeling are shown, in particular, problem offinal element zero thickness and problem of calculations bad convergence in various ANSYS modules. Conclusions about methods of mesh quality improvement are drawn. The directions of further researches are described.</p>
