Finite element mass matrix lumping by numerical integration with no convergence rate loss

Abstract Using numerical integration in the formation of the finite element mass matrix and placing the movable nodes at integration points causes it to become lumped or diagonal (block diagonal) with the optimal rate of energy convergence retained.
