Hi,

I need to use DM structures of type PETScInt.

I tried to use:

DM da_cu_types

Vec cu_types_local,cu_types_global

PetscInt,pointer :: cu_types_array(:,:,:)

Is this allowed? The cu_types_array is to be of integer type. Because I got 
into
problems compiling.
We do not support integer Vecs. You should use IS. What are you trying to 
do?

Hi,
I've a cfd code and I need to separate cells inside or outside a body. I 
denote
the inside /boundary /outside cells as type =2/1/0. I've a subroutine which
determines the type in parallel and hence I need a Vec with integer type. 
Based
on my description, can I use Is? Is there an example I can follow?
Thanks

Thank you.
