ogstools.mesh.utils module

ogstools.mesh.utils.node_reordering(mesh, method=1)

Reorders mesh nodes to make a mesh compatible with OGS6.

Parameters:

• mesh (UnstructuredGrid) – mesh whose nodes are to be reordered.

• method (int) –

  0: Reversing order of nodes for all elements.

  1: Reversing order of nodes unless it’s perceived correct by OGS6

  standards. This is the default selection.

  2: Fixing node ordering issues between VTK and OGS6 (only applies

  to prism-elements).

  3: Re-ordering of mesh node vector such that all base nodes are

  sorted before all nonlinear nodes.

Return type:

UnstructuredGrid

ogstools.mesh.utils.validate(mesh, strict=False)

Check conformity of mesh with OGS.

Parameters:

• mesh (UnstructuredGrid | Path | str) – pyvista mesh or path to the mesh file.

• strict (bool) – If True, raise a UserWarning if checkMesh returns an error.

Return type:

bool

ogstools.mesh.utils.check_datatypes(mesh, strict=False, meshname='')

Return type:

bool

ogstools.mesh.utils.reindex_material_ids(mesh)

Return type:

None

ogstools.mesh.utils.remove_data(mesh, datanames)

Return type:

None

ogstools.mesh.utils.axis_ids_2D(mesh)

Return the two axes, in which the mesh (predominantly) lives in.

Return type:

tuple[int, int]

ogstools.mesh.utils.reshape_obs_points(points, mesh=None)

Return type:

ndarray
