pygeon.grids.mortar_grid module

This module contains the MortarGrid class.

class pygeon.grids.mortar_grid.MortarGrid(*args, **kwargs)[source]

Bases: MortarGrid

A class representing a mortar grid, which is used for the discretization of interfaces between subdomains in a numerical simulation.

assign_sd_pair(sd_pair)[source]

compute_geometry()[source]

Computes the geometry of the MortarGrid.

Parameters:: sd_pair – The pair of subdomains.
Returns:: None

compute_ridges()[source]

Assign the face-ridge and ridge-peak connectivities to the mortar grid

Parameters:: sd_pair (Tuple[pp.Grid, pp.Grid]) – Pair of adjacent subdomains.
Returns:: None

assign_signed_mortar_to_primary()[source]

Compute the mapping from mortar cells to the faces of the primary grid that respects orientation.

Parameters:: sd_pair (Tuple[pp.Grid, pp.Grid]) – Pair of adjacent subdomains.
Returns:: A sparse matrix representing the mapping from mortar cells to primary grid faces. The matrix has dimensions num_primary_faces x num_mortar_cells.
Return type:: sps.csc_array

assign_cell_faces()[source]

Assign the connectivity between cells of the secondary grid and faces of the primary grid.

This method calculates and assigns the connectivity between the cells of the secondary grid and the faces of the primary grid. It uses the signed mortar values and the secondary-to-mortar interface function to determine the connectivity.

Parameters:: None
Returns:: None
