sgio.SGMesh

class sgio.SGMesh(points, cells, point_data=None, cell_data=None, field_data=None, point_sets=None, cell_sets=None, gmsh_periodic=None, info=None, cell_point_data=None)

Backend-neutral mesh container for Structure Genome I/O.

Stores geometry (points, cell blocks) and standard mesh data, plus cell_point_data for element-nodal fields. Attribute layout mirrors meshio.Mesh so adapters can access points / cells / point_data / cell_data / field_data / point_sets / cell_sets / gmsh_periodic / info uniformly. Interop with meshio goes through from_meshio() / to_meshio().

cell_point_data

Dictionary of element nodal data (data at nodes of each element). Structure: {name: [array_for_cell_block_0, array_for_cell_block_1, …]} where each array has shape (n_elements, n_nodes_per_element, n_components). This is used for storing element_node data like strain/stress at element nodes.

Type:

dict[str, list[np.ndarray]]

__init__(points, cells, point_data=None, cell_data=None, field_data=None, point_sets=None, cell_sets=None, gmsh_periodic=None, info=None, cell_point_data=None)

Methods

__init__(points, cells[, point_data, ...])
add_cell_data_from_dict(name, dict_data)	Attach per-element data (given as {element_id: value}) to the mesh.
add_point_data_from_dict(name, dict_data)	Attach per-node data (given as {node_id: value}) to point_data.
copy()	Return a deep copy of this mesh.
from_meshio(mesh)	Build an SGMesh from a meshio.Mesh.
from_pyvista(grid)	Build an SGMesh from a pyvista dataset.
get_cell_block_by_type(cell_type)
to_meshio()	Export this mesh to a meshio.Mesh.
to_pyvista()	Export this mesh to a pyvista.UnstructuredGrid for visualization.
