Annotations

$\mathtt{KDIAG}$	The key of element mass matrix diagonalization.
	$=1$	consistent matrices (default)
	$=2$	lumped matrices (Hinton-Rock-Zinkiewicz method)

Note
For $\mathtt{KDIAG}=2$ the program scales the entries on the main diagonal corresponding to translational degrees of freedom. Diagonal entries corresponding to rotational degrees of freedom are left unchanged.
