Abstract The truly Meshless Local Petrov-Galerkin (MLPG) method is extended to solve the incompressible Navier-Stokes equations. The local weak form is modified in a very careful way so as to ovecome the so-called Babu\~{s}ka-Brezzi conditions.

Numerical results for benchmark problems show that the MLPG method is very promising to solve the convection dominated fluid mechanics problems.
