Module Contents

class pymor.discretizers.builtin.grids.boundaryinfos.AllDirichletBoundaryInfo(grid)

Bases: pymor.discretizers.builtin.grids.interfaces.BoundaryInfo

BoundaryInfo where the boundary type ‘dirichlet’ is attached to each boundary entity.

Methods

mask	Return mask.

mask(boundary_type, codim)

Return mask.

retval[i] is True if the codim-codim entity of global index i is associated to the boundary type boundary_type.

class pymor.discretizers.builtin.grids.boundaryinfos.EmptyBoundaryInfo(grid)

Bases: pymor.discretizers.builtin.grids.interfaces.BoundaryInfo

BoundaryInfo with no boundary types attached to any boundary.

Methods

mask	Return mask.

mask(boundary_type, codim)

Return mask.

retval[i] is True if the codim-codim entity of global index i is associated to the boundary type boundary_type.

class pymor.discretizers.builtin.grids.boundaryinfos.GenericBoundaryInfo(grid, masks, assert_unique_type=(1,), assert_some_type=())

Bases: pymor.discretizers.builtin.grids.interfaces.BoundaryInfo

Generic BoundaryInfo storing entity masks per boundary type.

Methods

from_indicators	Create BoundaryInfo from indicator functions.
mask	Return mask.

classmethod from_indicators(grid, indicators, assert_unique_type=None, assert_some_type=None)

Create BoundaryInfo from indicator functions.

Parameters:

• grid – The Grid to which the BoundaryInfo is associated.

• indicators – Dict where each key is a boundary type and the corresponding value is a boolean valued function defined on the analytical domain which indicates if a point belongs to a boundary of the given boundary type (the indicator functions must be vectorized).

mask(boundary_type, codim)

Return mask.

retval[i] is True if the codim-codim entity of global index i is associated to the boundary type boundary_type.
