Harmonic ALE extension

Understand the Harmonic ALE extension 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: L_{ff}\mathbf d_f=-L_{fb}\mathbf d_b.

Troubleshooting

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