  A new recovery technique based on discretization corrected particle strength
exchange (DC PSE) operators is developed in this paper. DC PSE is a collocation
method that can be used to compute derivatives directly at nodal points,
instead of by projection from Gauss points as is done in many finite
element-based recovery techniques. The proposed method is truly meshless and
does not require patches of elements to be defined, which makes it generally
applicable to point clouds and arbitrary element topologies. Numerical examples
show that the proposed method is accurate and robust.
