cideMOD.numerics.fem_handler.interpolate(ex, V: dolfinx.fem.FunctionSpace | dolfinx.fem.Function, cells: ndarray | None = None, dofs: ndarray | None = None)[source]

Method to interpolate ex into V.

Parameters:

ex (Union[float,int,numpy.ndarray, dolfinx.fem.Function,) – ufl.Operator, dolfinx.Expression] The object to interpolate to.
V (Union[dfx.fem.FunctionSpace,dfx.fem.Function]) – The function (V or Function(V)) to interpolate into.
cells (Optional[numpy.ndarray]) – The cells (mesh entities) to interpolate over. If None then all cells are interpolated over. Used only if ex is an instance of dolfinx.fem.Function, ufl.Operator or dolfinx.Expression.
dofs (Optional[numpy.ndarray]) – The dofs (of V or Function(V)) to interpolate over. If None then all dofs are interpolated over. Used only if ex is an instance of float, int, numpy.ndarray.

Returns:

The interpolated function.

Return type:

dfx.fem.Function

cideMOD.numerics.fem_handler.isinstance_dolfinx(*args: Tuple[Any], dolfinx_classes=dolfinx_classes) → bool: This function checks whether a sequence contains instances of dolfinx classes. Returns a boolean or a list of booleans.
