- flatiron_tk.fem.boundary_conditions.build_dirichlet_bc(mesh, bnd_id, bc_val, function_space)[source]
Builds a Dirichlet boundary condition for a given boundary and value. :param mesh: The mesh object containing the boundary information. :type mesh: flatironx.mesh :param bnd_id: The boundary ID to apply the Dirichlet condition on. :type bnd_id: int :param bc_val: The value of the Dirichlet condition, which can be a function or a constant. :type bc_val: dolfinx.fem.Function or dolfinx.fem.Constant :param function_space: The function space to which the Dirichlet condition applies. :type function_space: dolfinx.fem.FunctionSpace
- Returns:
dolfinx.fem.dirichletbc
- Return type:
The Dirichlet boundary condition object.
:raises TypeError : If bc_val is not a dolfinx.fem.Function or dolfinx.fem.Constant.:
- flatiron_tk.fem.boundary_conditions.get_function_space_search(V)[source]
Returns the function space to search for dofs in case V is a subspace. If V is not a subspace, returns V itself. :param V: The function space to check. :type V: dolfinx.fem.FunctionSpace
- Returns:
if V is a subspace – tuple(dolfinx.fem.FunctionSpace, list mapping of the subspace to original space)
else – dolfinx.fem.FunctionSpace The function space to search for dofs.
