We report on the self-consistent field solution of the Hartree-Fock-Slater equations using the finite-element method far the three small diatomic molecules N2, BH and CO as examples. The quality of the results is not only better by two orders of magnitude than the fully numerical finite difference m

โฆ Synopsis
A fully numerical two-dimensional solution of the Schriklinger equation is presented for the linear polyatomic molecule Hi+ using the ftite element method (FEM). The Coulomb singularities at the nuclei are rectified by using both a condensed element distribution around the singularities and special elements. The accuracy of the results for the lo and 20 orbitak is of the order of IO-' au.

The calculation of net shapes is performed using the ยฎnite element method. A triangular element is developed for the modelling of the net. The main hypothesis is that the strain in each triangular element is constant, the net has only two directions of twine and the twines are elastic. The forces du
The calculation of stress intensity factors for complicated crack configurations in finite plates usually presents substantial difficulty. A version of the finite element method solves such problems approximately by means of special cracked elements. A general procedure for evaluating the stiffness
We present spin-polarized Hartree-Fock-Slater calculations performed with the highly accurate numerical finite element method for the atoms N and 0 and the diatomic radical OH as examples.
