Spectral-Like Accuracy in Space of a Meshless Vortex Method
The convergence of a meshless vortex method is studied numerically. The method uses core spreading for diffusion and radial basis function interpolation for spatial adaption of the Lagrangian particles. Spectral accuracy in space is observed in the absence of convection error, and second order of convergence is obtained it its presence.
