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