The element free Galerkin method (EFGM) requires moving least square (MLS) interpolation functions to approximate an
unknown function, which is made up of three components: a weight function associated with each node, a basis function and
a set of coefficients that depends on position. The weight function is non-zero over a small neighborhood at a particular node,
called support of the node. Using MLS approximation, the unknown velocity component f is approximated over the domain
