Abstract
In this paper we present a new method of mesh optimization which
automatically accounts for steep gradients. With this method, the user needs
no previous knowledge of the problem. The method is based on the concept of
error in the constitutive relation, coupled with an h‐version
remeshing procedure. The steep gradient regions are detected by using the
local errors, which are taken into account using the finite energy element.
Consequently the procedure can be extended to all estimators of
discretization errors. It is implemented in our code ESTEREF, a
post‐processor of error computation and mesh optimization that can be
used with any finite element code. Numerous examples show the capabilities of
the proposed method.
