The viscousflow active energy is different because of different morphology of fillers, and the system filled with small size filler has a lowviscousflow active energy.
When the number of grid is very great or viscous effects dominates or sometimes the speed of flow is low, the rate of convergence slows down dramatically, resulting in inefficient solution technique.
流体力学控制方程的数值求解过程中，当网格加密、粘性效应强或来流马赫数低的时候，流场收敛非常缓慢。

The coupled calculation for the viscous-inviscid interaction of three dimensional separated flow over dents at low speed has been made in the present paper.
