Member Data Documentation

◆ overlap

unsigned int PETScWrappers::PreconditionASM::AdditionalData::overlap

The amount of overlap between the subdomains. See PCASMSetOverlap.

Definition at line 1192 of file petsc_precondition.h.

◆ type

ASMType PETScWrappers::PreconditionASM::AdditionalData::type

The variant of the Additive Schwarz Method to use. See PCASMSetType.

Definition at line 1199 of file petsc_precondition.h.

◆ local_subdomains

LocalSubdomains PETScWrappers::PreconditionASM::AdditionalData::local_subdomains

The local subdomains for each processor. This is used to set the subdomains with PCASMSetLocalSubdomains(). If the vectors are empty, then the subdomains are generated by PETSc.
