Legacy stationary scalar reference (not an acoustic wave)

Understand the Legacy stationary scalar reference (not an acoustic wave) 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: -\nabla\cdot\left(K\nabla p\right)=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.
