firedrake.slope_limiter package

Submodules

firedrake.slope_limiter.limiter module

class firedrake.slope_limiter.limiter.Limiter(space)

Bases: object

Abstract Limiter class for all limiters to implement its methods.

Parameters:

space – FunctionSpace instance

abstractmethod apply(field)

Re-computes centroids and applies limiter to given field

abstractmethod apply_limiter(field)

Only applies limiting loop on the given field

abstractmethod compute_bounds(field)

Only computes min and max bounds of neighbouring cells

firedrake.slope_limiter.vertex_based_limiter module

class firedrake.slope_limiter.vertex_based_limiter.VertexBasedLimiter(space)

Bases: Limiter

A vertex based limiter for P1DG fields.

This limiter implements the vertex-based limiting scheme described in Dmitri Kuzmin, “A vertex-based hierarchical slope limiter for p-adaptive discontinuous Galerkin methods”. J. Comp. Appl. Maths (2010) http://dx.doi.org/10.1016/j.cam.2009.05.028

Initialise limiter

:param space : FunctionSpace instance

apply(field)

Re-computes centroids and applies limiter to given field

apply_limiter(field)

Only applies limiting loop on the given field

compute_bounds(field)

Only computes min and max bounds of neighbouring cells
