OSTI ID:7254105
A generalization of the rectangular geometry used in TEACH to four-sided isoparametric elements similar to those used in finite-element structural computation is developed. Elements are constructed with the aid of a special isoparametric transformation. Since the Jacobian of the transformation is constant along certain lines, the interpolation is referred to as ''isojacobic.'' A new two-dimensional hybrid differencing procedure is devised. Interpolation formulas are derived for the steady-state Navier--Stokes equation. 2 figures (RWR)
