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.
