class MatrixPreconditionerPinn(space, pde, **kwargs)

Bases: MatrixPreconditionerSolver

Matrix-based preconditioner for pinns.

Parameters:

• space (AbstractApproxSpace) – The approximation space.

• pde (EllipticPDE | TemporalPDE | KineticPDE | LinearOrder2PDE | RitzFormEllipticPDE | DivAGradUPDE) – The PDE to be solved.

• **kwargs –

  Additional keyword arguments:

  • in_lhs_name: Name of the operator to be used in the left-hand side assembly. (default: “functional_operator”)

Raises:

ValueError – residual size (bc, ic) is not a multiple of the number of labels
