int PCASMSetLocalSubdomains(PC pc, int n, IS *is)Collective on PC
pc | - the preconditioner context |
n | - the number of subdomains for this processor (default value = 1) |
is | - the index sets that define the subdomains for this processor (or PETSC_NULL for PETSc to determine subdomains) |
By default the ASM preconditioner uses 1 block per processor.
These index sets cannot be destroyed until after completion of thelinear solves for which the ASM preconditioner is being used.
Use PCASMSetTotalSubdomains() to set the subdomains for all processors.
