Meshfree methods are a modern alternative to classical mesh-based
discretization techniques such as finite differences or finite element
methods. Especially in a time-dependent setting or in the treatment of
problems with strongly singular solutions their independence of a mesh
makes these methods highly attractive. This volume collects selected
papers presented at the Sixth International Workshop on Meshfree Methods
held in Bonn, Germany in October 2011. They address various aspects of
this very active research field and cover topics from applied
mathematics, physics and engineering.
