PCAIRGetGridComplexity

Returns the grid complexity of the PCAIR multigrid hierarchy

Synopsis

PETSC_EXTERN PetscErrorCode PCAIRGetGridComplexity(PC pc, PetscReal *complexity)

Not Collective

Input Parameter

• pc - the PCAIR preconditioner context

Output Parameter

• complexity - the grid complexity of the hierarchy, or -1 if PCSetUp() has not yet been called

Note

Grid complexity is the total number of unknowns summed over all levels of the hierarchy, divided by the number of unknowns on the finest level.
