Mesh
(nodes, connectivity)[source]¶ Provides a class for general meshes.
Basically clues together the MeshGeometry and MeshTopology classes and provides interfaces for mesh refinement and function evaluation.
Parameters: - nodes (array_like) – The coordinates of the mesh nodes
- connectivity (array_like) – The connectivity array defining the mesh cells via their vertex indices
-
dimension
¶ The spatial dimension fo the mesh.
-
nodes
¶ The coordinates of the mesh nodes.
-
cells
¶ The incident vertex indices of the mesh cells.
-
facets
¶ The incident vertex indices of the mesh facets.
-
faces
¶ The incident vertex indices of the mesh faces.
-
edges
¶ The incident vertex indices of the mesh edges.
-
boundary
(fnc=None)[source]¶ Determines the mesh facets that are part of the boundary specified by the function fnc and returns a corresponding boolean array.
Parameters: fnc (callable) – Function specifying some part of the boundary for which to return the corresponding facets
-
refine
(method='uniform', **kwargs)[source]¶ Refines the mesh using the given method.
Parameters: method (str) – A string specifying the refinement method to use
-
eval_function
(fnc, points)[source]¶ Evaluates a given function in the global mesh points corresponding to the given local points on the reference domain.
Parameters: - fnc (callable) – The function to evaluate
- points (array_like) – The local points on the reference domain
Returns: nE x nP [x ...]
Return type:
