Detailed API Reference

class felupe.view.Scene

Base class for plotting a static scene.

mesh

A generalized Dataset with the mesh as well as point- and cell-data. This is not an instance of felupe.Mesh.

Type:

pyvista.UnstructuredGrid

サンプル

>>> import numpy as np
>>> import felupe as fem
>>>
>>> scene = fem.view.Scene()
>>> scene.mesh = fem.Cube(n=3).as_unstructured_grid()
>>> scene.mesh.point_data["Displacement"] = np.arange(81).reshape(27, 3) / 300

felupe.ViewMesh

Provide Visualization methods for a mesh with optional given dicts of point- and cell-data items.

felupe.ViewField

Provide Visualization methods for a field container.

felupe.ViewSolid

Provide Visualization methods for a field container or a solid body.

felupe.ViewMesh(mesh, point_data=None, cell_data=None, cell_type=None)

Provide Visualization methods for felupe.Mesh with optional given dicts of point- and cell-data items.

パラメータ:

• mesh (felupe.Mesh) -- The mesh object.

• point_data (dict or None, optional) -- Additional point-data dict (default is None).

• cell_data (dict or None, optional) -- Additional cell-data dict (default is None).

felupe.view.Scene

Base class for plotting a static scene.

felupe.ViewField

Provide Visualization methods for a field container.

felupe.ViewSolid

Provide Visualization methods for a field container or a solid body.

felupe.ViewField(field, point_data=None, cell_data=None, cell_type=None, project=None)

Provide Visualization methods for felupe.FieldContainer. The warped (deformed) mesh is created from the values of the first field (displacements). By default, the "Deformation Gradient" tensor, the "Logarithmic Strain" tensor and the "Principal Values of Logarithmic Strain" are evaluated as field-related items of the cell-data dict. Optional items of given point- and cell-data overwrite these default field-related cell-data items.

パラメータ:

• field (felupe.FieldContainer) -- The field-container.

• point_data (dict or None, optional) -- Additional point-data dict (default is None).

• cell_data (dict or None, optional) -- Additional cell-data dict (default is None).

• cell_type (pyvista.CellType or None, optional) -- Cell-type of PyVista (default is None).

• project (callable or None, optional) -- Callable to project internal cell-data at quadrature-points to mesh-points (default is None). Valid callables are project or extrapolate.

felupe.mesh

felupe.view.Scene

Base class for plotting a static scene.

felupe.ViewMesh

Provide Visualization methods for a mesh with optional given dicts of point- and cell-data items.

felupe.project

Project given values at quadrature-points to mesh-points.

felupe.ViewSolid(field, solid=None, stress_type='Cauchy', point_data=None, cell_data=None, cell_type=None, project=None, **kwargs)

Provide Visualization methods for felupe.FieldContainer and felupe.SolidBody. The warped (deformed) mesh is created from the values of the first field (displacements). By default, the "Deformation Gradient" tensor, the "Logarithmic Strain" tensor and the "Principal Values of Logarithmic Strain" are evaluated as field-related items of the cell-data dict. Optional items of given point- and cell-data overwrite these default field-related cell-data items.

パラメータ:

• field (felupe.FieldContainer) -- The field-container.

• solid (felupe.SolidBody or felupe.SolidBodyIncompressible or None, optional) -- A solid body to evaluate the (Cauchy) stress (default is None).

• stress_type (str or None, optional) -- The type of stress which is exported, either "Cauchy", "Kirchhoff" or None. If None, the first Piola-Kirchhoff stress (engineering stress in linear elasticity) is used. Default is "Cauchy".

• point_data (dict or None, optional) -- Additional point-data dict (default is None).

• cell_data (dict or None, optional) -- Additional cell-data dict (default is None).

• cell_type (pyvista.CellType or None, optional) -- Cell-type of PyVista (default is None).

• project (callable or None, optional) -- Callable to project stress at quadrature-points to mesh-points (default is None). Valid callables are project or extrapolate.
