Maxwell stress

Understand the Maxwell stress 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: \mathbf{T}_M=\epsilon\left(\mathbf{E}\otimes\mathbf{E}-\frac{1}{2}|\mathbf{E}|^2\mathbf{I}\right).

Troubleshooting

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