VecGetArrayAligned#
FORTRAN only. Forces alignment of vector arrays so that arrays of derived types may be used.
Synopsis#
Not Collective
Notes#
Allows code such as
type :: Field
PetscScalar :: p1
PetscScalar :: p2
end type Field
type(Field) :: lx_v(0:1)
call VecGetArray(localX, lx_v, lx_i, ierr)
call InitialGuessLocal(lx_v(lx_i/2), ierr)
subroutine InitialGuessLocal(a,ierr)
type(Field) :: a(*)
If you have not called VecGetArrayAligned()
the code may generate incorrect data
or crash.
lx_i needs to be divided by the number of entries in Field (in this case 2)
You do NOT need VecGetArrayAligned()
if lx_v and a are arrays of PetscScalar
