WebFeb 1, 1983 · T.J.R. Hughes et al.. Eleinent-by-element algorithm 247 where (6.2) With Vi in place of V in (5.4), calculations may be performed one element at a time thus obviating the need to form, store and operate upon the global array V. It may be shown that V,=V+0 (AT2), (6.3) that is, Vi is a first-order approximation of V.

It is absolutely stable, numerically dissipative, and much accurate than other dissipative time integration methods. It achieves high-frequency dissipation, while minimizing unwanted low-frequency dissipation. improving cash flow forecast
