Hi,
Inside my subroutine, I need to access the DA variable cu_types_array frequently.
So I need to call DMDAVecGetArrayF90 and DMDAVecRestoreArrayF90 before and after frequently.
Is this necessary? Can I call DMDAVecGetArrayF90 at the start and only call DMDAVecRestoreArrayF90 towards the end, where I don't need to modify the values of cu_types_array anymore?
Will this cause memory corruption?
You cannot use any other vector operations before you have called Restore.
Also, must the array be restored using DMDAVecRestoreArrayF90 before calling DMLocalToLocalBegin,DMLocalToLocalEnd?
Yes. Matt
