I have a 3d DMDA and a vector created by DMCreateGlobalVector. I want to<br>
visualize and therefore export a subset of the values, i.e. I want to<br>
"remove" some points at the boundary. For example, if the DMDA<br>
represents the domain [0,1]^3, I want to extract [0.25,0.75]^3.<br>
I already tried to create another (smaller) DMDA, use DMDAVecGetArray on<br>
both of them and then copy the values. The problem is that the vectors<br>
are distributed differently, so this approach leads to segfaults.<br>
Is there another way to do this?<br></blockquote><div><br></div><div>You can force the same layout using lx, ly, lz in the constructor.
