Return the i-th sub space. Args: i: Index of the subspace to extract. Returns: A subspace. Note:

@brief Create a subspace (view) for a specific component. @note If the subspace is re-used, for performance reasons the returned subspace should be s

The sub-topology.

@brief Indicate whether this function space represents a symmetric 2-tensor.

Element kernel that applies static condensation.

Return a unique directory name for this test function instance. Deletes and re-creates directory from previous test runs but lets the directo

Test that interpolation is correct in a function space.

Test adding entries to diagonal of sparsity pattern.

flake8 does not catch its warning code F822: whether the public API offered by the members of __all__ are implemented. We therefore manually c

Iterate over faces and sum area.

Placed this test here because it's mainly about detecting differing function spaces.

This test checks the original_coefficient_positions, which may change under differentiation (some coefficients and constants are eliminated).

Assembly on mesh where some ranks are empty.

Check special handling of packing of integration entities for exterior facets, which for any other co-dimensional entity is just a one-sided integ

Test assembly with boundary conditions and lifting.

Test assembly into a Quadrature function. This test evaluates a UFL Expression into a Quadrature function space by evaluating the Expression

Solve a two-field mass-matrix like problem with block matrix approaches and test that solution is the same.

Solve a two-field nonlinear diffusion like problem with block matrix approaches and test that solution is the same.

Assemble Stokes problem with Taylor-Hood elements and solve.

Assemble Stokes problem with Taylor-Hood elements and solve.

Tests assembly with Constant. The following test should be sensitive to order of flattening the matrix-valued constant.

Test basic assembly of PETSc Mat and compare with MatrixCSR assembly.

Test basic assembly of interior facet terms.

Manufactured biharmonic problem. Solved using rotated Regge or the Hellan-Herrmann-Johnson (HHJ) mixed finite element method in two-dimension

Test assembly of block vector with a zero block in the form.

Test that dof ownership is correctly handled for blocked function spaces.

Test that the correct number of boundary facets are computed.

Test that cell mismatch raises early enough from UFL.

Test packing coefficients with non-constant values.
