PCGASMDestroySubdomains

Destroys the index sets created with PCGASMCreateSubdomains() or PCGASMCreateSubdomains2D(). Should be called after setting subdomains with PCGASMSetSubdomains().

Synopsis

#include "petscpc.h" 
PetscErrorCode PCGASMDestroySubdomains(PetscInt n, IS *iis[], IS *ois[])

Collective

Input Parameters

• n - the number of index sets

• iis - the array of inner subdomains

• ois - the array of outer subdomains, can be NULL

Note

This is a convenience subroutine that walks each list, destroys each IS on the list, and then frees the list. At the end the list pointers are set to NULL.

Fortran Note

The arrays are not freed, only the IS within the arrays are destroyed
