Data

A symmetric octant of the cylindrical shell and its initial discretization, based on *p* = 2, *q* = 2, and *h* = *l*/2, are presented in Figure 27. A very coarse initial mesh can be seen in this figure. The thinness ratio equals *l*/*t* = 3.1415 × 10−2/0.03 × 10−2. The error data controlling the *hp*-adaptation are the admissible relative error value on the final mesh *γT* = 0.01 and the ratio of the admissible error values on the intermediate and final meshes *γI*/*γT* = 2.
