class pybamm.Mesh(geometry, submesh_types, var_pts)[source]#

Mesh contains a list of submeshes on each subdomain.

  • 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

Extends: builtins.dict


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


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


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

Return type:


class pybamm.SubMesh[source]#

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)[source]#

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

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

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