Abstract
The paper presents a parametric study on interpolation techniques based postprocessed
error estimation in finite element elastic analysis by varying important
parameters of recovery, interpolation scheme and type of patch construction. The quality
of error estimation with recovery parameters is compared in terms of local and global
effectivity of error estimation, rate of error convergence, and adaptively refined meshes.
A mesh free moving least square interpolation technique with proven reliability and
effectivity is introduced for improving the recovery of finite element solution errors. The
post-processed finite element solutions of elastic problems are presented for performance
study under different parameters of recovery technique. The study concludes that
recovery parameters of interpolation method have pronounced effect on the recovery of
finite element solution error and analysis in adaptive environment.
