是pdf格式的 回复后我会把题发过去的
Let T1, T2, . . . , T5 denote the meshes (with 16, 64, . . ., 4096 elements respectively) obtained
by applying five iterations of uniform refinement to T0, i.e. each triangle of the mesh is divided
into four triangles by joining the mid-points of adjacent sides with new edges. For mesh T1
answer the following questions:
(i) What are the element numbers of the elements which contain the node n1?
(ii) What are the coordinates of the nodes which belong to elements containing n1?
(iii) How many interior nodes and boundary nodes are there, respectively?
