4.7 EFFECT OF UNIFORM AND COSINE
DISTRIBUTIONS OF VIRTUAL NODES ON
CONVERGENCE OF RDQ METHOD
Several 1-D, 2-D, and elasticity problems are solved in this section by the
RDQ method. Their convergence analyses are performed by considering
the observations made from the consistency analysis. All the given prob-
lems are solved by the uniform and cosine distributions of virtual nodes,
and their rates of function convergence are compared. The distribution pat-
tern of the eld and virtual nodes is identied, which gives better rates of
convergence. For all the problems solved here, the global error is computed ...
