Enum Preconditioner 

pub enum Preconditioner {
    Lumped,
    Dirichlet,
}

Which FETI-DP preconditioner the dual PCG applies.

Dirichlet is the default: its condition-number bound is near mesh-independent, at the price of one interior solve per subdomain per iteration over Lumped’s cheap matvec — see projected_pcg’s own doc for the tradeoff in full.

Variants

Lumped

sum_s B_s K_dd,s B_s^T — a local matvec in place of a local solve.

Dirichlet

sum_s B_b,s S_s B_b,s^T — near mesh-independent convergence.
