作者研究了Darcy—Stokes问题在四边形网格上的P1-Q0统一非协调稳定化有限元逼近方法,证明了该方法的一致稳定性和离散问题解的存在唯一性,得到了误差估计,并在最后给出数值算例验证了理论结果.
In this paper, a unified nonconf presented for the Darcy-Stokes problem b method and the existence uniqueness tained. Numerical examples are given to v orming stabilized fini ased on quadrilateral of discrete problem a erify the theoretical r te element method of P1-Q0 elements is grid mesh. Then, the stability of this re proved. Error estimates are also obesults.
