Abstract
The paper deals with the methodological peculiarities of numerical simulation of separation processes in the context of the finite element method. It is shown that a poorly conditioned global stiffness matrix reflects the essence of the separation process. A method for monitoring the reliability and accuracy of the calculated data by means of the spectrum of a non-regularized global stiffness matrix is put forward. The possibility of assessing the spectrum of a global stiffness matrix through the sums of local matrices is shown.
