Coefficient form elliptic equation

Understand the Coefficient form elliptic equation relationship used by Coefficient Form PDE.

Where to find it

Coefficient Form PDE → 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(c\nabla u\right)=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.
