pygeon.numerics.projections module

This module contains functions for creating projection operators.

pygeon.numerics.projections.eval_at_cell_centers(mdg, discr, **kwargs)[source]

Create an operator that evaluates a solution in the cell centers.

This function takes a mixed-dimensional grid mdg and a discretization discr (optional) and returns an operator that can be used to evaluate a solution in the cell centers of the grid.

Parameters:

  • mdg (pg.MixedDimensionalGrid) – The mixed-dimensional grid.

  • discr (pg.Discretization) – The discretization used for the evaluation.

  • kwargs (dict) –

    Optional parameters:

    • as_bmat (bool): In case of mixed-dimensional, return the matrix as sparse sub-blocks. Default is False.

Returns:

The operator that evaluates the solution in the cell centers. If as_bmat is True, the operator is returned as sparse sub-blocks in sps.csc_array format. Otherwise, the operator is returned as a block matrix in sps.block_array format.

Return type:

sps.csc_array or sps.block_array
