pymor.discretizers.fenics.cg.discretize_stationary_cg(analytical_problem, diameter=None, degree=1, preassemble=True, solver=None)[source]

Discretizes a StationaryProblem with finite elements using FEniCS.

Parameters:

  • analytical_problem – The StationaryProblem to discretize.

  • diameter – If not None, diameter is passed as an argument to the domain_discretizer.

  • degree – polynomial degree of the finite element.

  • preassemble – If True, preassemble all operators in the resulting Model.

  • solver – The Solver to be used.

Returns:

  • m – The Model that has been generated.

  • data – Dictionary with the following entries:

    mesh:

    The generated dolfin mesh object.

    boundary_mask:

    Codim-1 MeshFunctionSizet indicating which boundary type a boundary facet belongs to.

    boundary_ids:

    Dict mapping boundary types to ids used in boundary_mask.

    unassembled_m:

    In case preassemble is True, the generated Model before preassembling operators.
