Harmonic particle velocity

Understand the Harmonic particle velocity relationship used by Pressure Acoustics.

Where to find it

Pressure Acoustics → equations

How to use it

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

Result

Equation: \mathbf v=-\nabla p/(i\omega\rho).

Troubleshooting

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