<br>
Inside my subroutine, I need to access the DA variable cu_types_array frequently.<br>
<br>
So I need to call DMDAVecGetArrayF90 and DMDAVecRestoreArrayF90 before and after frequently.<br>
<br>
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?<br>
<br>
Will this cause memory corruption?<br></blockquote><div><br></div><div>You cannot use any other vector operations before you have called Restore.</div><div> </div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">
Also, must the array be restored using DMDAVecRestoreArrayF90 before calling DMLocalToLocalBegin,DMLocalToLocalEnd?</blockquote><div><br></div><div>Yes.</div><div><br></div><div> Matt</div><div> </div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><span class="HOEnZb"><font color="#888888"><br>
