Unsymmetric meshless methods for operator equations [PDF]

Numerische Mathematik, 2009
The author proposes a general approach for approximatively solving the well-posed linear operator equations in normed linear spaces. The operators need not be elliptic and the problems can be posed in weak or strong form without changing the theory. The paper seems to be the first to provide a rigid mathematical foundation of certain variations of the `

A Frictionless Contact Algorithm for Meshless Methods

The International Conference on Computational & Experimental Engineering and Sciences, 2006
An approach to the treatment of contact problems involving frictionless sliding and separation under large deformations in meshless methods is proposed. The method is specially suited for non-structured spatial discretisation. The contact conditions are imposed using a contact potential for particles in contact.
