Rayleigh damping

Understand the Rayleigh damping relationship used by Equation contract.

Where to find it

Equation contract → equations

How to use it

Compare the terms, signs and units with your intended physical assumptions before choosing model inputs.

Result

Equation: \mathbf C=\alpha_M\mathbf M+\beta_K\mathbf K.

Troubleshooting

The equation describes the model assumptions; it is not a separate editable boundary condition. Check the parent physics page for setup and limitations.
