A two-level variational multiscale meshless local Petrov–Galerkin (VMS-MLPG) method for convection-diffusion problems with large Peclet number

•VMS method is constructed in the MLPG method.•Utilize the high and low orders Gauss integration to instead the large scale and small scale.•The numerical solution is accuracy and stability. It is challengeable to obtain the stable and accurate solutions of convection-diffusion problems with large P...
