| $\mathtt{ALPHA}$ $\mathtt{BETA}$ | The coefficients for the calculation of the Rayleigh element dumping matrix $\mathbf{C}$ (i.e., proportional dumping) using the fomula $\mathbf{C}=\alpha\mathbf{K}+\beta\mathbf{M},$ where $\mathbf{K}$ is the element stiffness matrix and $\mathbf{M}$ is the consistent element mass matrix. |
