For the nodal discretization X
2
the constructed RPI shape function of x
1
, and
the respective first order and second order partial derivatives, are presented in
Fig.
4.27
. It is visible that the RPI are capable to produce smooth and continuous
shape functions regardless the irregularity of the nodal discretization or the size of
the support-domain.
