values of the deection are identical, which indicates that the RDQ method
can effectively handle the distribution of random eld nodes.
The problem is further solved by the RDQ method with the spatial
domain discretised by either the uniform or random eld nodes coupled
with the uniform virtual nodes, and their results are compared with the
analytical and FEM solutions, as shown in Figure5.16b. Note in the gure
the slight effect of dispersion over time, as predicted from Equation (5.70).
