将非协调三角形Carey元应用于非线性Sobolev-Galpern型湿气迁移方程的有限元逼近格式,利用单元特性和误差估计技巧,在各向异性网格下得到了能量模的最优误差估计及相应的L2模的收敛结果。
This paper deals with the nonconforming triangular Carey element approximation to nonlinear Sobolev-Galpern type moisture transferring equation.Based on definition of the element and some approaches,the optimal error estimates of energy norm and convergence results of L2 norm are derived for anisotropic meshes.
