Meshfree or meshless methods were born to replace the traditional finite element in applications where meshing a complex geometry and/or excessive remeshing is involved.

This code, written by Vinh Phu Nguyen, implements one and two dimensional Element Free Galerkin (EFG) method which is one of the most common meshfree methods for elasticity. It also implements Partition of Unity based enrichment for weak and strong discontinuities. The method and the implementation are described in the following article
