Air-gap mesh extension

Understand the Air-gap mesh extension relationship used by Electrostatic Force.

Where to find it

Electrostatic Force → equations

How to use it

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

Result

Equation: \nabla\cdot(w\nabla\mathbf{u}_{mesh})=0.

Troubleshooting

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