Fixed mesh boundary

Understand the Fixed mesh boundary relationship used by Shape Optimization.

Where to find it

Shape Optimization → equations

How to use it

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

Result

Equation: \mathbf d_\Omega=\mathbf0\quad\mathrm{on}\ \Gamma_f.

Troubleshooting

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