Quadratic isoparametric elements which embody the inverse square root singularity are used in the calculation of stress intensity factors of elastic fracture mechanics. Examples of the plane eight noded isoparametric element show that it has the same singularity as other special crack tip elements,

## Abstract A finite element method approach for solving the threeβdimensional SchrΓΆdinger equation expressed in hyperspherical coordinates is applied to the calculation of rovibrational states of H~2~O and D~2~O. Comparisons to experimental values and other theoretical calculations are offered.
