定常不可压粘性流的两重网格算法(英文)

A Two-grid Method for the Steady Incompressible Viscous Flow

从数值实验上研究了定常不可压粘性流的两重网格算法。得出两重网格算法在和标准有限元算法保持同样精度的前提下,能节省CPU。因此两重网格算法是数值求解不可压粘性流的一种有效算法。

A numerical test is geven to study a twogrid method for the steady incompressible viscous flow. It follows that the convergence order of this method is the same as that of the usual finite element method. However, this twogrid method is effective for its saving a lot of CPU.
