Scalar weak equation

Understand the Scalar weak equation relationship used by Weak Form PDE.

Where to find it

Weak Form PDE → equations

How to use it

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

Result

Equation: \int_{\Omega} F(u,\nabla u,\mathrm{test}(u),\nabla\mathrm{test}(u))\,d\Omega=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.
