| In this paper,a mixed virtual element method of 3D axisymmetric Darcy flow is studied.With the help of axisymmetric property and the transformation of cylindrical coordinates,the 3D problem is transformed into a twodimensional problem.For the two-dimensional problem after dimension reduction,we propose a lowest-order mixed virtual element method,which proves that the error is optimal,and the theoretical results are verified by numerical examples. |
