Meshes

class pybamm.Mesh(geometry, submesh_types, var_pts)

Mesh contains a list of submeshes on each subdomain.

Extends: dict

Parameters

• geometry – contains the geometry of the problem.

• submesh_types (dict) – contains the types of submeshes to use (e.g. Uniform1DSubMesh)

• submesh_pts (dict) – contains the number of points on each subdomain

add_ghost_meshes()

Create meshes for potential ghost nodes on either side of each submesh, using self.submeshclass This will be useful for calculating the gradient with Dirichlet BCs.

combine_submeshes(*submeshnames)

Combine submeshes into a new submesh, using self.submeshclass Raises pybamm.DomainError if submeshes to be combined do not match up (edges are not aligned).

Parameters

submeshnames (list of str) – The names of the submeshes to be combined

Returns

submesh – A new submesh with the class defined by self.submeshclass

Return type

self.submeshclass

class pybamm.SubMesh

Base submesh class. Contains the position of the nodes, the number of mesh points, and (optionally) information about the tab locations.

class pybamm.MeshGenerator(submesh_type, submesh_params=None)

Base class for mesh generator objects that are used to generate submeshes.

Parameters

• submesh_type (pybamm.SubMesh) – The type of submesh to use (e.g. Uniform1DSubMesh).

• submesh_params (dict, optional) – Contains any parameters required by the submesh.
