Assemble a linear equation system (les) based on 2d location data (raster)

The linear equation system type can be set to N_NORMAL_LES to create a regular matrix, or to N_SPARSE_LES to create a sparse matrix. This function returns a new created linear equation system which can be solved with linear equation solvers. An 2d array with start values and an 2d status array must be provided as well as the location geometry and a void pointer to data passed to the callback which creates the les row entries. This callback must be defined in the N_les_callback_2d strcuture.

The creation of the les is parallelized with OpenMP. If you implement new callbacks, please make sure that the function calls are thread safe.

the les can be created in two ways, with dirichlet and similar cells and without them, to spare some memory. If the les is created with dirichlet cell, the dirichlet boundary condition must be added.

Parameters

les_type	int
geom	N_geom_data*
status	N_array_2d *
start_val	N_array_2d *
data	void *
cell_type	int – les assemble based on N_CELL_ACTIVE or N_CELL_DIRICHLET
call	N_les_callback_2d *

Integrate Dirichlet or Transmission boundary conditions into the les (2s)

Dirichlet and Transmission boundary conditions will be integrated into the provided linear equation system. This is meaningfull if the les was created with N_assemble_les_2d_dirichlet, because in this case Dirichlet boundary conditions are not automatically included.

The provided les will be modified:

Ax = b will be splitted into Ax_u + Ax_d = b

x_u - the unknowns x_d - the Dirichlet cells

Ax_u = b -Ax_d will be computed. Then the matrix A will be modified to

Parameters

les	N_les* – the linear equation system
