fenicsxconcrete.finite_element_problem.base_material module

class MaterialProblem(experiment: Experiment, parameters: dict[str, Quantity], pv_name: str = 'pv_output_full', pv_path: PosixPath | None = None)

Bases: ABC, LogMixin

class SensorDict

Bases: dict

Dict that also allows to access the parameter p[“parameter”] via the matching attribute p.parameter to make access shorter

When to sensors with the same name are defined, the next one gets a number added to the name

add_sensor(sensor: BaseSensor) → None

clean_sensor_data() → None

abstractmethod compute_residuals() → None

Implemented in child if needed

abstractmethod static default_parameters() → tuple[Experiment, dict[str, Quantity]]

returns a dictionary with required parameters and a set of working values as example

delete_sensor() → None

export_sensors_metadata(path: Path) → None

Exports sensor metadata to JSON file according to the appropriate schema.

Parameters:

path – Path Path where the metadata should be stored

import_sensors_from_metadata(path: Path) → None

Import sensor metadata to JSON file and validate with the appropriate schema.

Parameters:

path – Path Path where the metadata file is

abstractmethod setup() → None

Implemented in child if needed

abstractmethod solve() → None

Implemented in child if needed

update_time() → None

class QuadratureFields(measure: Measure | None = None, plot_space_type: tuple[str, int] = ('DG', 0), mandel_stress: Expr | Function | None = None, mandel_strain: Expr | Function | None = None, stress: Expr | Function | None = None, strain: Expr | Function | None = None, degree_of_hydration: Expr | Function | None = None, damage: Expr | Function | None = None, compressive_strength: Expr | Function | None = None, tensile_strength: Expr | Function | None = None, youngs_modulus: Expr | Function | None = None, yield_values: Expr | Function | None = None, history_scalar: Expr | Function | None = None)

Bases: object

A dataclass to hold the quadrature fields (or ufl expressions) of the problem, at least those that we want to plot in paraview. Additionally, the measure for the integration and the type of function space is stored. The list of names should be extendend when needed.

Examples

Since this is a dataclass, the __init__ method is automatically generated and can be used to selectively set fields. All fields that are not explicitely set are set to their default value (here None).

>>> q_fields = QuadratureFields(measure=rule.dx, plot_space_type=("Lagrange", 4), stress=some_function)

compressive_strength: Expr | Function | None = None

damage: Expr | Function | None = None

degree_of_hydration: Expr | Function | None = None

history_scalar: Expr | Function | None = None

mandel_strain: Expr | Function | None = None

mandel_stress: Expr | Function | None = None

measure: Measure | None = None

plot_space_type: tuple[str, int] = ('DG', 0)

strain: Expr | Function | None = None

stress: Expr | Function | None = None

tensile_strength: Expr | Function | None = None

youngs_modulus: Expr | Function | None = None

class SolutionFields(displacement: Function | None = None, velocity: Function | None = None, temperature: Function | None = None, nonlocal_strain: Function | None = None)

Bases: object

A dataclass to hold the solution fields of the problem. The list of names should be extendend when needed.

Examples

Since this is a dataclass, the __init__ method is automatically generated and can be used to selectively set fields. All fields that are not explicitely set are set to their default value (here None).

>>> fields = SolutionFields(displacement=some_function, temperature=some_other_function)

displacement: Function | None = None

nonlocal_strain: Function | None = None

temperature: Function | None = None

velocity: Function | None = None

fenicsxconcrete.finite_element_problem.linear_elasticity module

class LinearElasticity(experiment: Experiment, parameters: dict[str, Quantity], pv_name: str = 'pv_output_full', pv_path: str = None)

Bases: MaterialProblem

Material definition for linear elasticity

compute_residuals() → None

Implemented in child if needed

static default_parameters() → tuple[Experiment, dict[str, Quantity]]

static method returning a description dictionary for required parameters

Returns:

description dictionary

pv_plot() → None
