Choice of parameters of meshing using estimates of conditionality

Abstract

The paper shows the dependence of matrix condition indicators and multicollinearity indicators on the dimension of the original problem mesh. Examples from an open integrated platform for the numerical simulation of continuum mechanics OpenFOAM tasks are given. The behavior of conditionality indicators and that of the diagonal dominance indicator are shown to be the same. An example of determining mesh dimensions with the help of the diagonal dominance indicator is given.
