Harmonic pressure acoustics

Understand the Harmonic pressure acoustics 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: -\nabla\cdot(\rho^{-1}\nabla p)-\omega^2p/K=Q_m.

Troubleshooting

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