Struct SparseNearfieldIlu

pub struct SparseNearfieldIlu { /* private fields */ }

Expand description

Sparse ILU preconditioner for FMM near-field

Uses only the near-field blocks to build an ILU factorization, avoiding the O(N²) cost of building a dense matrix.

Implementations§

Source §

impl SparseNearfieldIlu

Source

pub fn from_slfmm( near_blocks: &[NearFieldBlock], cluster_dof_indices: &[Vec<usize>], num_dofs: usize, threshold: f64, ) -> Self

Create from SLFMM near-field blocks

Builds a sparse ILU factorization using only the near-field structure, which is O(N) entries instead of O(N²).
