This problem is also solved in the earlier section of convergence analysis,
but only for the cosine distribution of virtual nodes combined with the uni-
form and random distributions of eld nodes. It is additionally solved here
for the uniform virtual nodes combined with the uniform and random eld
nodes, and their convergence rates are compared.
The third 1-D example is a local high gradient problem with a force term
containing an exponential expression. Exponential function can be approx-
imated by an innite series, such as the power series by Taylor expansion.
It is solved here by includi ...
