Mesh

class felupe.Mesh(points, cells, cell_type=None)

A mesh with points, cells and optional a specified cell type.

Parameters

• points (ndarray) – Point coordinates.

• cells (ndarray) – Point-connectivity of cells.

• cell_type (str or None, optional) – An optional string in VTK-convention that specifies the cell type (default is None). Necessary when a mesh is saved to a file.

points

Point coordinates.

Type

ndarray

cells

Point-connectivity of cells.

Type

ndarray

cell_type

A string in VTK-convention that specifies the cell type.

Type

str or None

npoints

Amount of points.

Type

int

dim

Dimension of mesh point coordinates.

Type

int

ndof

Amount of degrees of freedom.

Type

int

ncells

Amount of cells.

Type

int

points_with_cells

Array with points connected to cells.

Type

array

points_without_cells

Array with points not connected to cells.

Type

array

cells_per_point

Array which counts connected cells per point. Used for averging results.

Type

array

as_meshio(**kwargs)

Export the mesh as meshio.Mesh.

Parameters

filename (str, optional) – The filename of the mesh (default is mesh.vtk).

copy()

Return a deepcopy of the mesh.

Returns

A deepcopy of the mesh.

Return type

Mesh

disconnect()

Return a new instance of a Mesh with disconnected cells.

save(filename='mesh.vtk', **kwargs)

Export the mesh as VTK file. For XDMF-export please ensure to have h5py (as an optional dependancy of meshio) installed.

Parameters

filename (str, optional) – The filename of the mesh (default is mesh.vtk).

update(cells)

Update the cell and dimension attributes with a given cell array.
