A correction technique for the dispersive effects of mass lumping for transport problems. - Computer Methods in Applied Mechanics and Engineering. - 2013. - Vol. 253. - P. 186-198] applied to pure transport and convection-diffusion problems. In particular, it is found that increasing the number of corrections reduces the accuracy for problems with diffusion; however all the corrected schemes are more accurate than the consistent Galerkin formulation in this case.
