Until now it has been considered that the method of increasing accuracy by mesh concentration gives good results. The fact that the mesh concentration of triangular finite elements does not always lead to more exact results has been proved in this paper. Analytical proofs illustrated by numerical examples and conclusions concerning the methods of area discretization have been formulated. These methods can be used in the mesh generating program.
