Meshfree & EFG methods

PerennialII

I'm looking for any material concerning meshfree methods, in particular element-free Galerkin method for solving PDEs ... haven't worked with the topic for the last couple of years and I'm considering on doing an implementation for a "changing solution domain" PDE problem for the mechanical equilibrium problem with some special tweaks. Any recent theoretical, software etc. info would be really useful, thanks !
