−β α . This problem is solved by including up to second order mono-
mials in the polynomial basis of function approximation, and by separately
combining the total 25 uniform and random distributions of the eld nodes
at the start of computation with the total 33 × 33 cosine virtual nodes.
The initial and nal nodal distributions are shown in Figure 6.15. The
