Hi,<br>
<br>
I have used DMDACreate2d for my code and then use:<br>
<br>
call DMLocalToGlobalBegin(da,b_rhs_semi_local,INSERT_VALUES,b_rhs_semi_global,ierr)<br>
<br>
call DMLocalToGlobalEnd(da,b_rhs_semi_local,INSERT_VALUES,b_rhs_semi_global,ierr)<br>
<br>
to construct the global DM vector b_rhs_semi_global<br>
<br>
Now I want to get the values with ghost values in a 2d array
locally which is declared as:<br>
<br>
real(8), allocatable :: array2d(:,:)<br>
<br>
I guess I should use DMDAGetGhostCorners to get the
corressponding indices and allocate it. But what should I do
next? How can I use something like VecGetArrayF90 to get to
the pointer to access the local vector?<br>
<br>
I can't use DMDAVecGetArrayF90/DMDAVecRestoreArrayF90 since
I'm using intel fortran and they can't work. I can't use
gfortran at the moment since I've problems with HYPRE with
gfortran in 3D.<br>

<div>Are you certain of this? That used to be true, but the
current version should work for any F90.</div>

I just tested 3.3-p1 and it still doesn't work (example ex11f90 in
dm). Is there a chance petsc-dev can work?<br>
