typedef enum SchurState SchurState

Schur complement class for a PETSC based linear system.

Linear system consists of Matrix, inversion matrix, RHS, solution and pointer to Complement. It provides methods for:

  • set complement system
  • create distribution of complement system
  • create inversion matrix of system
  • form Schur complement and rhs
  • solve and resolve system

Usage example: SchurComplement * schur = new SchurComplement(is, &distr);

... // allocation and assembly of matrix

LinSys_PETSC * ls = new LinSys_PETSC( schur->make_complement_distribution() ); schur->set_complement( ls ); schur->solve();

Input record is passed to the complement system.
