This paper presents a h-adaptive scheme of the placement of the collocation
points for the element-free Trefftz method.
The present scheme is applied
to the two-dimensional potential problem in order to confirm its validity.
The element-free Trefftz method can solve the problem by only taking the
boundary collocation points when the domain under consideration is gov-
erned by linear and homogeneous differential equation.
Therefore, the input
data generation is much simpler than the other solution procedures.
however, the accuracy is strongly dependent on the placement of the collo-
cation points, this paper presents the h-adaptive scheme of the placement.
The similar schemes were already presented by Xiaoping et al.fl] for the
plate bending problem and by Kita e...
