`forms`

Form containers

Structured form containers used by the symbolic FEM workflow.

`DomainIntegral`

A domain integral ∫ integrand dx over a 1D domain. Call .as_integral() to get a SymPy Integral object.

`BoundaryContribution`

A boundary term from integration by parts. Stores the expression, coordinate, evaluation point, and optional label. Call .evaluate() to substitute the coordinate and simplify.

`WeightedResidual`

The complete weighted residual before splitting into bilinear/linear forms. Contains domain integrals and boundary contributions. Call .as_expression() to combine into a single SymPy expression.

`WeakForm`

The split weak form with bilinear part a(u,v) and linear part F(v). The bilinear form contains terms with both trial and test functions. The linear form is the right-hand side.
