Example: choose a conservative form

With model and mesh from a scalar elliptic setup in modeling:

python

import eqiora

plan = eqiora.resolve(
    model, mesh=mesh,
    spatial=eqiora.fvm.CellCenteredTpfa(),
    formulation=eqiora.formulation.IntegralConservative,
)

This pairs a conservative mathematical form with a finite-volume policy. Use PrimalGalerkin with scalar Q1 finite elements and MixedGalerkin with mixed velocity/pressure elements. The formulation, the spatial method, and the model must all be compatible.
